As President Donald Trump tries to elude oversight in Congress for his actions, including recent dealings with Ukraine, Trump's personal lawyers have made a far-reaching claim that could remove a judicial check on a president's alleged transgressions.Trump's lawyers have argued in a federal case to be heard Wednesday that the Constitution shields the president from any criminal investigation -- not just from actual prosecution -- while he holds office.Among their legal justifications, Trump lawyers quote a 2009 law review essay written by now-Supreme Court Justice 583

Attempted murder charges were filed Saturday against a Philadelphia man accused of shooting six police officers during an hours-long standoff, according to court records.The suspect, Maurice Hill, 36, was denied bail during a preliminary arraignment, online court records show.The formal charges, including multiple counts of aggravated assault and assault of a law enforcement officer, were filed three days after Hill allegedly barricaded himself in a North Philadelphia row house when police attempted to serve a narcotics warrant.Hill also faces counts of assault of a law enforcement officer, reckless endangerment, gun possession and drug conspiracy. His next court appearance is September 5.The Philadelphia District Attorney's office declined comment, saying prosecutors will announce charges against Hill and four others at a news conference Monday.Hill's attorney did not immediately respond to a request for comment.Before the standoff, the suspect already had 984

B. Don Russell wasn’t thinking about preventing a wildfire when he developed a tool to detect power line problems before blackouts and bigger disasters.The electrical engineering professor at Texas A&M University figured he might save a life if his creation could prevent someone from being electrocuted by a downed live wire.But fire prevention may be his product’s biggest selling point in California and other places that have experienced devastating wildland blazes blamed on electrical equipment.“If we can find things when they start to fail, if we can find things that are in the process of degrading before a catastrophic event occurs, such as a downed line that might electrocute someone or a fire starting or even an outage for their customers, that’s kind of the Holy Grail,” Russell said.The technology he bills as a one-of-a kind diagnostic tool called Distribution Fault Anticipation is now in use in Texas and being tested in California by Pacific Gas & Electric Co. and Southern California Edison. The utilities have been blamed for some of the most destructive and deadliest fires in California.Texas A&M said the technology will also be tested in New Zealand and Australia, which is currently reeling from destructive wildfires.The tool detects variations in electrical currents caused by deteriorating conditions or equipment and notifies utility operators so they can send a crew to fix the problems, Russell said.It can anticipate many problems in their early stages — sometimes years before they cause an outage or present a greater hazard during high winds when utilities are now pre-emptively shutting off power to prevent sparking wildfires.Before the technology was developed, electric companies often didn’t know they had a problem until there was a failure or a customer called to report sparks on power lines or a loss of electricity.“The assumption the utility has to make today is it’s healthy until we get a call that says somebody’s lights (are) out,” Russell said. “By then the fire’s started or the outage has happened or the person’s electrocuted.”Pedernales Electric Cooperative Inc. that serves about 330,000 customers outside San Antonio and Austin, Texas, began implementing the system after successful tests that began in 2015. The utility serves areas so rural that before the technology was installed, electricity powering a pump on a well could have been off for days before being detected by a farmer.The devices installed at substations are now trouble-shooting all kinds of problems, said Robert Peterson, principal engineer for the utility.“We’ve found tree branches on the line. Failing arrestors. Failing capacitors. Failing connections,” Peterson said. “It’s pretty amazing.”In California, the testing process has just begun and there are no results yet, according to PG&E and SoCal Edison.In Southern California, the software is running on just 60 of Edison’s 1,100 circuits in the utility’s high-risk fire zone, which accounts for about a quarter of its total circuits.It’s just one of several tools the utility is testing to continue to modernize its system.“There is no silver bullet,” said Bill Chiu, managing director of grid modernization and resiliency at SoCal Edison. “This is really more of a preventive measure. ... The important point is this will be one of the suite of technology that will help us better assess the condition of the grid.”Chiu said the technology was not at the point where it could be used to determine where to shut off power when dangerous winds are forecast during dry conditions. He also said it won’t pinpoint problems but can help dispatch crews closer to the source of equipment that needs to be fixed, saving time that would be wasted patrolling miles of power lines.One question is whether the technology is economically feasible to deploy across tens of thousands of miles of power lines, Chiu said.At an expense estimated between ,000 to ,000 per circuit, it could cost the utility million in its high-risk fire area and that doesn’t include installation, operation and maintenance costs.That’s a fraction of what a moderate wildfire sparked by a utility could cost, Russell said.PG&E, which is testing the technology on nine circuits, was driven into bankruptcy protection this year while facing at least billion in losses from a series of deadly and destructive wildfires in 2017 and 2018.SoCal Edison recently agreed to pay 0 million to local governments to settle lawsuits over deadly wildfires sparked by its equipment during the last two years. That figure doesn’t include lawsuits by thousands who lost their homes in those fires or family members of 21 people killed when a mudslide tore down a fire-scarred mountain. Two other people were never found.Bluebonnet Electric Cooperative found the cost was feasible and has installed it on about a sixth of its circuits for the utility that has about 100,000 customers in Central Texas, said Eric Kocian, chief engineer and system operations officer.While the system has helped proactively diagnose problems and detect the cause of outages, the university team that developed it can often find problems the utility’s control room operators don’t detect.Pedernales Coop is working with an analytics company to streamline the analysis of the myriad information the software evaluates to find and fix problems in a day, Peterson said.Russell said he never had a hint the device his research team created 15 years ago would have fire prevention applications until a series of bad wildfires in Texas in 2011. They were focused on keeping power systems safe and the lights on.“It’s obvious now in today’s context of the drought that we’ve had in California and other places,” Russell said. “Serendipitously, that’s where we find ourselves today.” 5838

An English teacher with Metro Nashville Public Schools has been placed on leave pending a disciplinary review for a homework some parents considered to be inappropriate. The assignment itself has sparked conversation about race and how to handle tough subjects in the classroom.The homework in question was assigned to 30 students at Cane Ridge High School in Antioch as they discussed "Fences," a play and film adaptation exploring the topic of race as a father struggles to provide for his family. The handout given to students asked them to write a one-page paper on the derogatory term "n-word" and answer several questions including how the word is racist and how it is used. In the assignment provided by a parent, the term was spelled out. The play uses the language frequently. The parent, who wanted to remain anonymous, said she was hurt and felt the conversation about race and derogatory terms should be taught by parents and not the school. She wanted more awareness about how sensitive the topic is and preferred prior notification. The teacher involved has been with MNPS since 2015 and received no disciplinary actions in the past. Spokesperson Sean Braisted of MNPS said the assignment has been retracted and canceled. In a statement, MNPS Director Dr. Adrienne Battle said, “The homework assignment given out at Cane Ridge High School was offensive, inappropriate, and out-of-line with the standards of MNPS. I sincerely apologize to students, families, and community members who may experience pain or trauma as a result of this incident.""It's difficult for sure in this particular context if the assignment is appropriate, but based on what I see, those are the kinds of questions we need to engage with our young people," said Cornelius Vanderbilt Distinguished Professor of Education Richard Milner.Milner said having deep conversations on tough subjects like this is in the classroom is essential and can be beneficial to help young people engage in difficult conversations outside of the classroom. However, he stresses a lot of work is required to communicate the meaning and history behind the word beforehand."Thinking about and asking young people to engage with the word without talking and being deliberate about the historical nature of it can do more harm than good," he said.Milner said while most teachers tend to have really good intentions, sometimes teachers are unprepared to address what might be considered the difficult issues, and should have proper tools. Since the incident, a student started an online petition showing support for the teacher. So far it has garnered more than 800 virtual signatures. The student said the teacher is "being persecuted for trying to prepare us for the real world by gifting us with the ability to think critically."Battle said the actions of the teacher will be investigated by Human Resources. The administration is working with the Equity and Diversity team on follow-up actions or training for any other faculty at the school who may have been involved in the decision to approve the assignment. 3089
