We call this:
Felony Assault
Felony Battery
Felony Kidnapping
Felony Armed Robbery
Felony Breaking and Entering
Using a Firearm during the commission of a VIOLENT FELONY
Every cop there should be in Prison for not less than 30 years, personally I would ask for LIFE and maybe even the Death Penalty for their FELONY GANG BEHAVIOR.
There are Federal charges which could be brought, also. See 18USC242.
