You know the saying "One bad apple will spoil the bunch"? Yeah, that's what goes on unfortunately. Like the guy in Florida a year ago that kept his 20ft Burmese with out a ROC permit, and it made national headlines when FWC came to take it away. Notice now Florida can't have those snakes.
It stinks, but those few bad pet owners that have no idea what they are doing, and are highly uneducated about animals like snakes and other creatures, ruin it for everyone when they allow them to escape, especially out of the house. Not much we can do to stop moron owners unfortuantely.
