You're so confused. No one is up in arms about police shootings involving armed suspects in the act of a crime who pull guns out on cops.
People are up in arms because so many confused people like yourself use the existance of armed criminals as a justification to treat any unarmed black men as if they are armed criminals. No, gang shootings in Chicago don't justify shooting unarmed black kids anywhere in the country.
The idea you put forth that a police officer would be charged with a hate crime for shooting an armed suspect is so ***** stupid.
