OETA/PBS next week's Nature: Invasion of the Giant Pythons

Quote:

An examination of a problem in Florida's Everglades National Park involving giant Burmese pythons. The nonnative snakes, some of which were released into the wild by pet owners (others escaped from refuges during hurricanes), have upended the ecosystem.

Why do I feel this will have a lot of misinformation?

That was originally aired in February, in fact you can watch the full episode on PBS's website right now.

Having the displeasure of watching the show. Narrator keeps saying "probably released pets".
