Taking away a constitutional right without due process should not make it past the first judge.
Exactly.
The right way to handle people suspected to be dangerous mental cases is to have someone who is really close to them to bring charges which would be heard by a judge.
With competent representation for the defendant.
What makes all of this so difficult, and beyond a simple executive order, is that in almost every single mass shooting, the first thing you hear is all of those close to the shooter on TV telling allfor the world to hear, “He was such a nice boy. I never dreamed he would ot something like this”.
So simple solutions will not fix it.
What we really need is some way to find out who has bombs under their bed, plans drawn up, etc. That would reduce the number of these incidents.
But the truth is that there are no perfect solutions that result in zero incidents.
“Better ten guilty go free than one man be falsely imprisoned” will forever be a valid and decent principle.
