No, I wasn't referring to the gun lock issue. The Kohl amendment was a 2nd degree amendment, being a change to the Boxer amendment. I seem to remember a Kohl amendment to which Craig referred as being a "slight" change to S. 1805, but I don't see it on Thomas.gov. I thought Kohl had offered some clarifying language to which Craig agreed regarding the underlying S. 1805.
I certainly don't consider the gun lock amendment "subtle", and I'm very creeped out that it got 70 votes. The CPSC oversight is very scary and a chance for real mischief.
BTW, it is already mandatory here in NY State that ALL firearms sold come with a gun lock. Elliot spitzer, I'm sure, will have fun with that one, whether he remains AG or is elected Governor.
