Whoa now folks, here is what the NBC affiliate is reporting:

"Diana Carr (pictured, right) says her son, David Michael Keene, has been diagnosed with severe emotional problems. She said he was institutionalized seven times between the ages of 8 and 13.

"He's had a continuing problem with impulse control, and an exaggerated belief that he was in more danger than he was in at times, causing him to respond in a way that was more excessive or out of line with what was going on," Carr told News4's Pat Collins. "

Because the shooter's mother makes these claims--and note that there is not a claim of "institutionalization" occurring since the shooter was 13 years old--doesn't mean they are fact. What is a fact is this guy shot at another motorist on the Geo Washington Parkway on a Sunday afternoon from his BMW. A mother's claim doesn't a fact make here. What other sort of claim would this guy be making besides a mental health defense to get his ass out of a sling here? I note the parents also haven't posted bail for their son. I'll say this guy has an "impulse control" problem all right. That is what jails are for--guys like him who can't control their impulse to shoot at other drivers on the freeway.
