AUSTIN, Texas -- Valarie Allman has been throwing discus for 10 years.“When you throw a discus it takes about two seconds, and it’s a combination of power, of grace, of strength… I like to think of it as a dance still," Allman said.She started sophomore year of high school. But it’s her dance background that she credits for her quick progression in the sport.“I had a weird knack for it," Allman said. "I think all those years of learning choreography and spinning and doing pirouettes weirdly carried over to the discus, and it kind of just seemed like a good fit right from the start.”Multiple days every week, she trains hard in the gym guided by her coach Zebulon Sion.“I’m responsible for every facet of her training," Sion said. "So that includes the strength-training concepts, if we do any type of running, fitness oriented things, plyometrics, and then of course the actual throwing.”Their chemistry is undeniable.At only 25 years old, Allman is considered a pro athlete. Her rigorous training is fueled by her desire to be a part of the next Olympics.“When I graduated college, I think that was the motivation to keep training. I missed the team in 2016 by three feet and it was kind of in that moment that I realized that I really wanted to try again,” Allman said.Consistency, discipline, attention to detail. Allman’s focus didn’t falter until she found out the 2020 Olympics had to be postponed.“It was pretty heartbreaking," Allman said. "I mean, to feel like you’ve put in so much to be prepared for it and to be healthy and to do everything right to feel like you’d have a chance to make the team and then for it to be postponed I think it kind of just made me question everything.”“Her motivation to throw kind of was gone a bit for her for a while," Sion said. "And then we kind of got to a point after a month, month-and-a-half of training going well in terms of lifting and training -- our goal was to get fit, get strong and refine the technical model that she has to get to a point where we could be at our best if that opportunity would come.”That opportunity did come. On August 1st in Rathdrum, Idaho, Allman beat the Women's Discus American Record.“I threw 70 meters and 15 centimeters, and the previous record was 69 meters and 17 centimeters.”The three-foot difference that kept her from qualifying for the Olympics in 2016 is the difference she surpassed to become the first and only American woman to throw past 70 meters.“When you’re throwing that type of distance, three feet is significant. So to break it by almost three feet was huge actually,” Sion said.“When they measured the throw and they read out the numbers and it started with a seven I instantly burst into tears. I was absolutely shocked,” Allman said.Allman says 70 meters is the ultimate barrier. In the past 20 years, only two other women in the world have thrown past 70 meters.“Now looking back it’s wild the think it was just a sliver of a difference of giving up when we were on the brink of something incredible,” Allman said.“We could have called it we could have said 2020 is a bust ya know let’s move on," Sion said. "But the amount of time, energy, effort all the things to put in over five months of uncertainty and then for that to happen – I don’t know if I could be more proud.”The same day of her record-breaking throw was the exact day she would have been competing in Tokyo had the Olympics continued. However, with her dedication to improvement, Sion believes there’s a great future ahead of Allman.“I mean I think the goal is just to throw farther and to keep throwing far more often. I mean it’s pretty simple,” Allman said.Even more simple when you’re having fun. 3692

As President Donald Trump and Republicans attempt to reverse the results of last week’s presidential election in Pennsylvania, a significant case often cited by Trump’s supporters has lost steam.The House Oversight Committee, led by Democratic Congresswoman Carolyn Maloney, announced that Richard Hopkins has “recanted” his claim of election fraud in Erie County, Pennsylvania. Hopkins had previously accused fellow USPS employees of changing the date of ballots submitted after the election. 501

As New Haven, Connecticut, Fire Chief John Alston Jr. spoke to reporters about a spate of drug overdoses on Wednesday, he heard shouting coming from behind him."We're getting another call of a person," Alston said.He quickly helped coordinate the response, and then returned to the microphone.That scene came on the same day that as many as 71 people in the area of New Haven Green were believed to have overdosed on some form of K2, according to New Haven police spokesman Officer David Hartman.New Haven Green is a large park and recreation area in the city's downtown.The patients included people of various ages and demographics, Alston said."It's a nationwide problem. Let's address it that way," he said. "It's a nationwide problem that people are self-medicating for several different reasons, and every agency -- police, fire, medical hospitals -- all are strained at this time. This is a problem that's not going away."New Haven police said one person is in custody.Rick Fontana, director of Emergency Operations for New Haven, said the patients had symptoms of increased heart rates, decreased respiratory rates and a lot of vomiting. Some people were unconscious, others were semi-conscious.No one has died, but two individuals are considered to be in serious, life-threatening condition. Some individuals who were released from the hospital needed to be treated a second time for an additional apparent overdose, Fontana said.K2 is a synthetic cannabinoid related to marijuana that is frequently laced with other drugs, said Dr. Sandy Bogucki of the Yale School of Public Health.In two cases, Narcan was not effective in the field, but a high dose of Narcan at the hospital was effective in combating the overdose effects. Authorities confirm the substance was synthetic cannabis and that other drugs weren't involved in the substance.The response from emergency responders has been "tremendous," Fontana said.He said authorities have been treating and sometimes transporting six or seven people at one time and the actions of first responders have been "lifesaving.""We hope this is coming to an end, but it's too early to tell."The-CNN-Wire 2162

Authorities are investigating interference with police radio communications, websites and networks used by law enforcement and other officials during recent U.S. protests over the death of George Floyd in Minneapolis.Although the efforts to disrupt police radios and take down websites in Minnesota, Illinois and Texas aren’t considered technically difficult hacks, federal intelligence officials warned that law enforcement should be ready for such tactics as protests continue.Authorities have not yet identified anyone responsible or provided details about how the disruptions were carried out. But officials were particularly concerned by interruptions to police radio frequencies during the last weekend of May as dispatchers tried to direct responses to large protests and unrest that overshadowed peaceful demonstrations.During protests in Dallas on May 31, someone gained access to the police department’s unencrypted radio frequency and disrupted officers’ communications by playing music over their radios, according to a June 1 intelligence assessment from the U.S. Department of Homeland Security.Dallas police did not respond to questions about the incident.The assessment, which was obtained by The Associated Press, attributes the Dallas disruption to “unknown actors” and does not say how they accessed the radio frequency. It warned that attacks of various types would likely persist.“Short-term disruptive cyber activities related to protests probably will continue — various actors could be carrying out these operations — with the potential to use more impactful capabilities, like ransomware, or target higher profile networks,” the assessment warns.The assessment noted similar problems with Chicago police’s unencrypted radio frequencies during large downtown protests on May 30 followed by reports of arson, theft and vandalism. Chicago police also have not said how the radio frequencies were accessed, but an official with the city’s Office of Emergency Management and Communications told the Chicago Sun-Times that the tactic was “very dangerous.”Police around the country have encrypted their radio communications, often arguing that it’s a way to protect officers and block criminals from listening in on widely available phone apps that broadcast police radio channels. But media outlets and local hobbyists have been frustrated by the changes, which also prevent them from reporting on issues pertaining to public safety.The Department of Homeland Security issued a separate warning this week reporting that personal information of police officers nationwide is being leaked online, a practice known as “doxxing.” According to the report obtained by the AP, information shared on social media included home addresses, email addresses and phone numbers.Law enforcement agencies have been targeted by online pranksters or hackers in recent years, including by some who claimed to be motivated by on-the-ground protests against police tactics. For example, the hacking collective Anonymous claimed responsibility for the defacement of local police departments’ websites in 2012 as protesters clashed with officers during the Occupy Wall Street movement.Individuals who self-identified as being part of the collective also claimed to have accessed dispatch tapes and other Ferguson Police Department records in 2014 after a white police officer shot and killed Michael Brown, an 18-year-old black man.Like other government entities, law enforcement agencies in recent years have been frequently targeted by ransomware attacks, in which a perpetrator virtually locks up a victim’s computer files or system and demands payment to release them.The prevalence of cyberattacks — which can cause physical damage or far-reaching disruption — and less severe online trickery, such as stealing passwords, has given law enforcement agencies more experience at fending off efforts to take down their websites or access critical information. But hackers adapt too, and governments with fewer resources than private companies often struggle to keep up, said Morgan Wright, chief security officer for the cybersecurity company SentinelOne.“The biggest concern they have right now is the safety of their communities, the safety of their officers,” Wright said of how law enforcement agencies view cyberthreats amid large demonstrations and unrest. “But if you look at what underpins everything we use to communicate, collaborate and operate, it’s all technology.”As large protests gathered steam after the May 25 death of Floyd, a handcuffed black man who died after a white Minneapolis police officer used his knee to pin his neck down for several minutes, Minnesota Gov. Tim Walz said state networks had been targeted. He described the activity as a “a very sophisticated denial of service attack.”But experts said the strategy of bombarding a website with traffic is common and doesn’t always take a high level of skill, counter to Walz’s description. Minnesota’s Chief Information Officer Tarek Tomes later said state services weren’t disrupted.But the efforts got a lot of attention, partly due to unverified online claims that Anonymous was responsible after years of infrequent activity. The decentralized group largely went quiet in 2015 but is still known globally based on headline-grabbing cyberattacks against Visa and MasterCard, the Church of Scientology and law enforcement agencies.Twitter users also made unverified claims that Anonymous was behind recent intermittent outages on the city government’s website in the Texas capital of Austin. Their posts indicated that the disruption was retribution for police officers shooting a 20-year-old black man in the head with a bean bag during a May 31 protest outside of police headquarters.The injured protester, identified by family as Justin Howell, remained hospitalized Wednesday in critical condition.The city’s IT department was looking into the site’s issues, but a spokesman said Monday that he couldn’t provide any information about the cause. He said the website was still experiencing a high volume of traffic.“You should have expected us,” an account purporting to be Anonymous’ posted on Twitter. It also warned that “new targets are coming soon.”The collective’s approach — anyone can act in its name — makes it difficult to verify the recent claims of responsibility. But Twitter accounts long affiliated with Anonymous shared them, said Gabriella Coleman, a professor at McGill University in Montreal who has studied the Anonymous movement for years.People with more advanced and disruptive hacking skills often drove peak instances of attention for Anonymous, and it’s not clear whether that type of activity will resume, she added.“There’s a lot of things going on in the background, people are chatting,” Coleman said. “Whether or not it materializes is another question. But certainly people are kind of aroused and talking and connecting.”___Foody reported from Chicago.
