One think I learned from friends who took anti-depressants, is that very bad thing happens when you go cold turkey and just quit. You’re supposed to wean yourself from them. Turns out the NIU gunman had stopped taking his:
“He had stopped taking medication and become somewhat erratic in the last couple of weeks,” Grady said, declining to name the drug or provide other details.
I’ve never known someone who went this crazy, but the friends I’ve known who have taken anti-depressants and stopped cold weren’t the same people while they were going through withdrawal. These are drugs that are altering your brain chemistry. I wouldn’t be surprised to find that psychosis is a rare side effect of the withdrawal process.
We do find out which guns the killer used:
 Two of the weapons — the pump-action Remington shotgun and a Glock 9mm handgun — were purchased legally less than a week ago, on Feb. 9, authorities said. They were purchased in Champaign, where Kazmierczak was enrolled at the University of Illinois.
He apparently had an Illinois FID, though it doesn’t say that in this article, I read that elsewhere. Â There’s really no way you can stop someone who has no criminal or mental history, which this guy didn’t.
Expect a lot of talk from the media about how the Glock is particularly deadly, rather than a common side arm. No doubt there will also be calls to pass a magazine ban in Illinois in response to this, even though their licensing of gun owners provisions and various other controls did nothing to prevent this.
