Note to Rob's House: I am not a leftist. I am strongly anti-regulation and anti-union, among many other non-leftist views. I am culturally liberal, fiscally quite conservative. I have some uncharacterizable views, for example I believe in open borders with little to no government services, etc.
(You, by contrast, are basically an admitted homophobe, among other bigoted viewpoints.)
Anyhow - the issue of police shootings is less about the police departments and more about the juries who acquit the offending officers...
