Unintentional release due to a catastrophe is very different then intentional release by an irresponsible pet owner. It is still yet to be proven how the burms became established in the everglades, but this point is rarely made in the media. The point that is being made is that the general public can not be trusted as owners.

If one reviews the common themes found in the press it always comes down to pet owners dumping their pets. This is a critical plank in the foundation for arguing against private ownership of large constrictors. The other must be how dangerous they are to the public because that seems to be a common theme as well.

Here is the University of Florida fact sheet which is where many of the media outlets have drawn their talking points from.

"Unable to handle their giant snakes, and unable to find new homes for them, some owners illegally release them into the wild."
