Good call by the D.A. This is the worst nightmare for those who tried to push several myths before CCW was legalized in Wisconsin. They include:
There will be wild shootouts, or many accidents with guns
People will have their guns taken from them and used on them.
People legal carrying guns makes you less safe.
Law abiding citizens with guns never stop crimes.
So far, there has been no evidence of the first two, although admittedly at some point there will be incidents of some kind. But the last two are shattered for good.
