It is telling that you equate "brandishing" with concealed carry. Interesting, but not surprising.A common sense gun law is to have comprehensive background check laws, instead of partial ones with loopholes.
Common sense gun laws is recognizing that wherever guns are banned, tragedy ensues. And wherever guns are prevalent, peace and lawfulness ensues.
So you believe the federal government should force schools, for example, to allow anyone to walk in and around a school, brandishing a firearm,
and do so unmolested.
Seriously, people, this is what we're up against.
