OK, let's sat someone is dangerous and has guns... The state uses a law like this to come take them...

We now have a dangerous person that's royally pissed , but they are (temporarily) disarmed... So what happens when they drive their SUV into a Walmart and start clubbing people with a medieval flail?

If they are truly dangerous, they need incarceration or professional help... (but how do you punish somebody for something they haven't done yet?) But these liberal whacks think the best choice is to take his toys away?
