As Yiden we are on the forefront in fight against bigotry of course.
What happens is, when there is a shocking case (such as unfortunate killing of Mr. Floyd) there is a shock, and from the shock it can go to extreme. There is a justifiable fear of extremism. The hype against ALL police, in and of itself is already so dangerous, which that leads to irrational voices.
May our father in heaven protect all of us. Gd bless our beautiful USA.
