What do you think a beat cop does on a daily basis that requires the threat of armed violence from that cop in particular? "gang culture" and "lots of firearms" are not reasons for beat cops to be armed on a daily basis. "how many times has a police officer been shot during routine daily events?" - this is not relevant. Having a gun does not protect you from being shot. Quite the opposite, in general. If a police officer is attempting to make an arrest and experiences armed resistance, then it is of course necessary to have a small, dedicated part of the police force that is authorized to use firearms.
