Your neighbors...

You know, for most of my life, I've been against the death penalty, but based on the examples below, I'm beginning to re-think this. I know, if we wait long enough these people will all either kill themselves or be killed by their neighbors, but they'll do alot of damage in the meantime. Anybody got any suggestions ? Is the entire country being ravaged by idiots ?

A San Francisco man has been convicted of murder and mayhem for using a meat cleaver to castrate and kill his father, whom he blamed for coddling him and fostering his drug addiction, authorities said Tuesday.
"The defendant's mother, who is on disability, testified that she too indulged her son. She said that while she shopped and went job hunting with him, she also used methamphetamine with him and took him to solicit transvestite prostitutes." (geez, I appreciate my parents a little more now)

"In January, Bertone, 55, was arrested after police raided his home, allegedly finding everything from illegal weapons to methamphetamine.
Neighbors had complained that he was a headache, blasting everything from police radio dispatches to salsa music with a bank of speakers on the roof of his home at 336 Lathrop Ave. He installed surveillance cameras up and down the block."
