I am guessing a cop is going to get suspended over this at the very least. the cop might even be guilty of a felony because he used his position to detain some ie kidnap.
You are joking, right?
These are police. They are above your civilian laws. They could have shot the lawyer, claimed they thought she had a gun in her briefcase, and then spent two weeks on paid vacation before returning to duty, and getting an award for making the tough call.
When was the last time a cop has been actually found guilty of an unjustified killing?
