Okay, so say you're in a shopping centre, no kevlar, and some gangster shoots somebody. The police patrolling the shopping centre do not have guns. So basically, you have a homicidal maniac running around the town, and all the police have to stop him is a Big Stick. If they had guns, they could take him down easily with a shot to the leg or something, it does not always mean murdering them. And citizens should be able to walk around the town without fearing for their safety.
