Usually, two groups argue, shout, shoot and have all eyes on them, instead.
If that happens more often, more guns need to go downtown, but in trained hands and more obstacles providing cover need to be present, such as trees in large pots.
Forbidding fire arms in certain areas just will create easy victims for guys like the Las Vegas stabbed but still capable of finding their car keys, what you may call a sad reality.
Or necessary evil...
