Just held up local gun control. Only thing that can't be banned is a gun in your own home for self defense.

since there's not really very much to stop someone from going to the next county to buy weapons and ammunition, is there?

It's also about how the community expresses desire for terms of use of firearms within their jurisdiction.

In that way, it seems to me, that an incorporated community isn't any different from other corporations that have rules about fire arms possession/use on their property.

Dealing with failure to comply, aka 'breaking the law', is the basic job we expect from a process called law-enforcement. Anticipation that a law would be broken isn't a compelling reason of itself to not create the law.

Burglary and assault for example, happen all the time and the law cannot prevent those acts from occurring. However, the law does provide for penalties to be applied to convicted and admitted violators.

I didn't think so.

Most states have a pre emption law just because a firearm shouldn't have to worry about being legal from city to city, town to town, county to county.
Only the state should be setting firearm laws so there isn't a patchwork of laws throughout the state.

would that also work for you?
