Violence against innocent people and their property is criminal and the police and civil authorities have a duty to stop those who perpetrate it. From Lew Rockwell at lewrockwell.com:
Last Monday, May 25, George Floyd died in police custody after an arrest in Minneapolis. Floyd had moved to Minneapolis trying to “start a new life” after a long prison sentence. According to one account, “Floyd was charged in 2007 with armed robbery in a home invasion in Houston and in 2009 was sentenced to five years in prison as part of a plea deal, according to court documents.”
On the night of his death, Floyd was arrested after a complaint he had tried to pass a counterfeit $20 bill. He struggled with the police and, after he was put in a patrol car, he fell out of the car onto the pavement. At that point, Derek Chauvin, one of the arresting officers, left Floyd on the ground and restrained him by putting his knee on Floyd’s neck. He kept his knee on Floyd’s neck for nearly 9 minutes. Floyd lost consciousness and died about I hour later. Chauvin clearly used excessive force against Floyd.
I have so far left out the key fact that you need to know in order to understand what has happened since then. Floyd was black. Immediately after Floyd died, a hue-and-cry went up that claimed that Floyd’s death was just the latest in a long list of incidents in which police kill blacks.
