You'd still need to hide if you happened to have a gun in the event that you don't, I don't know, want to get shot.

A gun is a weapon, not armor.

Also, having a gun out might make you a target for the police. They don't know that you're a good guy.

We had a shooter situation at my apartment complex not long ago and the police were on scene before I had time to unlock my pistol.

Consider, though, those living outside major population centers, where the police response time can be on the order of 10 to 30 (or more) minutes and there's an active shooter situation. There's very little that can be done to mitigate damage done by the shooter or prevent him from escaping in that span of time.
