Because when you watch the news for instance they dont state why the snakes are dangerous or the situation that made them that way. I.E. Open enclosure, Laziness, Hunger from lack of food, and so on..
The media will simply state
"Young child missing, Python found with remains inside."
or "Child missing, Python found around remains."
This is a conspiracy a friend and I had a while ago when authorities found a Burm that had tried eating a kid.
After the investigation is done the parents were put in JAIL. The investigation found the kid had been shaken or beaten to unconsiousness. Is it far fetched to believe that the parents did the ultimate evil and only knew one way to cover it up and that was the "snakes FAULT"
Here is the story:

This is why snakes are seen as evil. Not that people with bad intentions are any better. And again for the sake of those who might post, this was a conspiracy theory a friend and I had but the story itself is true. As far as weather or not the parents injured the kid and tried covering it up this is not proven.
