Black Lives Matter activists are holding their first Black National Convention Friday, a virtual event that will adopt a political agenda calling for slavery reparations, universal basic income, environmental justice and legislation that entirely re-imagines criminal justice reform.The gathering follows Democratic and Republican party conventions that laid out starkly different visions for America. It also comes on the heels of yet another shooting by a white police officer of a Black man — 29-year-old Jacob Blake — in Kenosha, Wisconsin, that sparked days of protests, unrest and violence.And it comes on the same day as a commemoration of the 1963 March on Washington, where the families of an ever-growing list of police and vigilante violence victims will appear with civil rights leaders.Friday’s live-stream broadcast will include policy proposals on such issues as voter suppression, reproductive rights, inequality in public education, housing insecurity and inter-communal violence, according to its agenda, shared exclusively with The Associated Press.“These are absolutely public policies that the Democratic Party, state and local officials, or anyone who is looking to serve Black people can take up now,” said Jessica Byrd, who leads the Electoral Justice Project of the Movement for Black Lives, a coalition of more than 150 Black groups organizing the event.In 2016, the coalition released its “Vision for Black Lives” policy platform which included early proposals for defunding police. The new agenda revamps much of that original platform with specific proposals that could lead to an eventual abolition of the criminal justice system as it exists today.It takes on the pledge Wednesday by Vice President Mike Pence at the Republican National Convention, who defended police and called for an end to unrest in cities where arson, looting and violence have followed peaceful protests over police brutality.“Under President Trump, we will always stand with those who stand on the thin blue line,” Pence declared. “And we’re not going to defund the police. Not now, not ever.”Similar to the Democratic and Republican conventions, much of Friday’s Black Lives gathering will feature pre-taped conversations, performances and other presentations, including 28 mini- documentaries on the issues and addresses by Black organizers in California, Minnesota, Kentucky and Wisconsin.Earlier this week, yet another flashpoint put police brutality in the national spotlight: The police shooting Sunday in Kenosha that left Blake paralyzed, according to his lawyers. The protests and unrest that followed left two people dead Tuesday.“Anyone who is watching, who is both enraged or looking for action, will find a space” in the Black National Convention, Byrd said.The nearly four-hour-long event, livestreaming on the website BlackNovember.org, was directed by award-winning writer and filmmaker dream hampton, who won acclaim last year for the “Surviving R. Kelly” docuseries. Hosts include activist and TV actress Angelica Ross of “Pose” and “American Horror Story” fame, along with Phillip Agnew and Kayla Reed, veterans of the Trayvon Martin protests and Ferguson Uprising, respectively.“I have long thought there was great storytelling to do in the world of Black activism,” hampton told the AP. “The real stars have always been these organizers who get things done.”Speakers include Patrisse Cullors, a co-founder of the Black Lives Matter Global Network; Tarana Burke, founder of the #MeToo movement; Raquel Willis, a writer and transgender rights activist; and Eddie Glaude, chairman of the Center for African American Studies at Princeton University.The Black National Convention was originally planned to take place in-person in Detroit, the nation’s Blackest major city. But as the coronavirus pandemic exploded in March, organizers shifted to a virtual event.Friday’s convention is expected to be the largest gathering of Black activists and artists, albeit virtual, since the historic 1972 National Black Political Convention in Gary, Indiana, which concluded with the introduction of a national Black agenda.Earlier in the day on Friday, the Rev. Al Sharpton and Martin Luther King III, a son of the late civil rights icon, will hold a commemoration of the 1963 March on Washington for Jobs and Freedom. Sharpton and King will be joined at the Lincoln Memorial by the families of George Floyd, Breonna Taylor, Rayshard Brooks and Blake, as well as representatives of the Martin and Eric Garner families.The Black National Convention broadcast begins after the D.C. march has concluded.“This is truly for Black people, to sit on our porches, or on the train, or socially distanced in a park, and to be like, ‘Look at us,’” Byrd said. “There is nothing that we can’t do. And everything good in this country, we’ve been a part of.”___Morrison s a member of the AP’s Race & Ethnicity team. Follow him on Twitter: https://www.twitter.com/aaronlmorrison. 4986

BARTOW, Fla. — Police say two middle school girls, who worship Satan, armed themselves with knives in a foiled plot to violently kill classmates and drink their blood at school on Tuesday.The 6th and 7th-grade girls attend Bartow Middle Schol in Bartow, Florida, police say. At 1:30 p.m. Tuesday, the Bartow Police School Resource Officer assigned to the school was summoned to the principal's office in reference to an armed juvenile complaint.The investigation revealed that the students armed themselves with knives, and planned on attacking fellow students during the school day."Fortunately, they were intercepted by school staff hiding in a bathroom during class time prior to carrying out their plans," Bartow Police said in a press release.According to the Bartow Police Department, a student warned a teacher on Monday about one of the girl’s mentioning that “something bad” would happen in building 500 of the middle school. The superintendent said extra officers were at the school on Tuesday as a result of this warning. After one of the girl’s mother received a robo-call alerting her that her child was not in second period, she called the school to inform teachers that the child should be there.Bartow Middle School staff immediately began to search the campus. They found the two girls in a bathroom. The girls were holding a goblet which an administrator suspected was being used to drink alcohol.Once in the principal’s office, the girls were told to empty their pockets, which revealed a knife and knife sharpener. After that, their bags were searched, and several weapons including a pizza cutter and butcher knife were found on the girls. The two admitted to planning to kill students as they entered the bathroom.“They noted that they wanted to kill at least 15 people and were waiting in the bathroom to find smaller kids that they could overpower to be their victims,” Bartow Police Chief Joe Hall said. “I believe that these two small children. I’m going to call them small children, they are only 11 and 12, seriously sat down and plotted to do bodily harm to another student at school.”The police chief said that over the weekend, the two girls plotted and planned their attempt to kill fellow students at the middle school. The investigation also revealed messages between the two, detailing the plans for their attack. The last message sent between the girls stated, "Today is health lessens thank Satan we're doing this in a bit," according to an arrest report.When asked about motivation, the girls reportedly told police that they were Satan worshipers. According to police, the girls planned to drink their victims’ blood out of the goblet they were found with. They also discussed eating their victims' flesh and leaving body parts at the school's entrance before killing themselves."Killing all of these students was in hopes it would make them worse sinners ensuring that after they committed suicide ... (they) would go to hell so they could be with Satan," the arrest affidavit reads.Both juveniles were arrested and removed from the campus, their names are not being released because they are both minors. No students or adults were harmed.Police say that notices have been sent to the parents of students at Bartow Middle School informing them of the situation. 3380

BEIJING — China has become one of the last major countries to congratulate U.S. President-elect Joe Biden, who is expected to make few changes to U.S. policy toward Beijing on trade, technology and other conflicts that have soured relations. China, along with Russia, avoided joining the throng that congratulated Biden last weekend after he and running mate Kamala Harris secured enough Electoral College votes in the Nov. 3 election to win the White House. "We respect the choice of the American people. We congratulate Mr. Biden and Ms. Harris,” Chinese foreign ministry spokesman Wang Wenbin said. 609
