The post had to do with the idiotic idea of having "gun free zones" as a thing of the past. The post showed what having handguns in a nightclub can do. Even if the guns were forbidden to be there, it was NOT open season on the one shooter who started the shootout but rather general mayhem by all that were armed.

Bars, clubs, restaurants, churches, sporting events should all be gun free zones. Enforcement by all means available.
