Sorry -
This is totally the parents fault. If you are a black Mom, and you do not drill it into your kids head that the Police will shoot you if you point ANYTHING that even remotely resembles a gun at them, you have failed.
I'd start at like age two..
" What does the kitty say?"
" Meow meow"
"What does the duck say?"
"Quack quack"
" What happens when you point something at the Police Man?"
" Bang Bang"
I am going to make an Urban - "See and Say".---
Seriously - if I was black and my kid pointed a hot dog, in a bun, at a cop, I would be like " What are you doing!! Cop will think that's an AK -47 !"
