I will have to watch it, but I do think it's a good idea to have kids get instructions on how to handle interactions with police officers. Understand what they want, and how to handle it.
White kids don't need that instruction. White people don't need training on how to not get killed by police. Sometimes white people are killed by police, but as a group, just being white isn't a consideration when dealing with police. Asshole people escalate things, asshole cops escalate things, but in general, white people don't have to worry too much about being pulled over for a tail light out or speeding. Other than the worry about their driving record or being able to pay the fine, white people have to have something else going on to really fear simply being pulled over.
That footage from the classroom is the most telling and disheartening part of the whole video. That black kids have to be specially trained to avoid being killed by specially trained officers with authority and weapons should give anyone pause, even those who don't understand what racism means.
You should watch the whole video, though. John offers a very rational case for policing the police, regardless of what you might think about specific cases argued on this board.
