I think Florida is on the right track with micro chipping, secure enclosures, and licensing ... all of which prevent impulse buying that could result in irresponsible releases and allow responsible owners to continue doing what they've always done.
I think that the other side to that coin is serious scientific surveys of the burmese pythons in the Everglades (I've heard numbers everywhere from 10,000 - 250,000 ... they have to be just guessing at this point) ... trap programs ... and grant programs for open admission, licensed, giant snake rescues.
In my opinion, each state should be able to determine what is best for it's own citizens and the ecosystems within that particular state.
