Ok then pass this new system at the state level. I was trying to devise a realistic way to quickly prosecute these crimes to actually act as a deterrent and to obtain legitimate justice.
Just as the democRATS aren't going to stop mass shootings by passing more gun "control" and, my favorite, gun "safety" laws, after the fact.
Bad, evil psychotic people will not be deterred by stricter laws. If they were concerned about laws against killing, they wouldn't be out killing to begin with.
You want "legitimate justice"? Shoot and kill them before they can kill again.
