Stop in for a cup of coffee

I have been telling the wife this alot more lately. To dramatically cut down on shootings just do a better job controling the ammo, like show a ID for it? I know to serialize it also is a big NRA no no.
Those that can't or couldn't buy it will get it.
But I agree we need tighter control in certain aspects for some.
It's difficult though to stop crazy and angry especially both.
