From the other thread but it fits here as well.

"Permitted individuals are free to take the specimens or euthanize them on site at their discretion."

Honestly I think that killing of a species we deem as invasive is ignorant always have and this is not just the case of snakes. I believe that an animal that can survive in an environment should be allowed to they further develop North America's weak ecosystem and help natural selection in the areas they establish themselves in. I know they were introduced improperly however this is the case with many non native plants and animals that end up becoming a positive change in the ecosystem. Humans have always wanted to control the earth and the ecosystem and we will eventually be the most negative impact on it ironically.

/end rant.
