The police lives matter deal is a touchy subject because there are crooked and racist cops out there, also, there are good ones that just do their job, and go home to their family. I personally know many police officers like this. But with tentions already high right now between the police and black people, I personally would've picked a neutral side to take the distraction off of those kids.
Those Vidor kids are regular kids. Many of them aren't racist as well as the total population as i know and are friends with several Vidorians... The few 'old heads' are the ones responsible for continuing the hate from the horrible past.
