Which "loophole" is that? The one that prevents the army from reporting you to the FBI for "excessive drug use" - a matter of privacy that the left would be screaming against if it were for any other purpose :

Schumer, who authored the 1994 assault weapons ban with Sen. Dianne Feinstein (D-Calif.), said he sees three areas with "possible bipartisan cooperation" to tackle in the wake of the shooting.

First, he said, is looking at the laws in terms of someone who is mentally ill buying a gun; next is his initiative to make the armed forces notify the FBI of certain failed candidates; and third is a congressional effort to limit magazine clips to 10 rounds.

Sen. Frank Lautenberg (D-N.J.) and Rep. Carolyn McCarthy (D-N.Y.), with the backing of gun-control groups, are drafting a bill that would ban the sale of magazines such as the one reportedly used by Loughner.

"The only reason to have 33 bullets loaded in a handgun is to kill a lot of people very quickly," Lautenberg said in annoucing plans to introduce the bill when the Senate returns. "These high-capacity clips simply should not be on the market."

Coburn said it's critical that guns laws don't "limit the ability to defend yourself."

The absolute worst that happens in the wake of these tragedies is both Republicans and Democrats getting ambitious about "addressing the problem." Inevitably, they end up stomping on our rights in the name of appearing to "do something" which doesn't help, and is usually wrong headed and stupid.

Loughner did not progress far enough in his army induction to be evaluated by a mental health professional. Short of that, it is a matter of privacy regarding any other maladies or problems he might have that would prevent his induction into the military. Who determines what's "excessive" as far as drug use? And why should that necessarily prevent you from buying a gun? And what happens if you seek help and get back to normal? What of your rights then?

Too many questions and too many eager beaver politicians trying to make it look like they are acting to solve a problem.,
