What animal isn't? Piranhas are innocent. Deadly venomous snakes are innocent. Does that mean just anyone should have the right to buy and keep them?
Sorry but I have to LOL at this!!! Piranhas?!?! oh goodness you can't lump those in there.... Piranhas are the biggest wussy fish there is. We have a school of 9 piranhas that are about 4-5 in long so far. The moment you put anything in the tank (your hand) that is unfamiliar they SCAT! They flip out and run for dear life! They hide in the plants and lay on their sides.... even if it's a new and large food item they've never seen before. It takes them about a half hour to work up the courage to swim over to it. Piranhas are incredibly harmless unless you slit your wrists and go for a swim in their native habitat where there are hundreds of thousands of them. They are not bloodthirsty and angry. There is simply no comparison between piranhas, large constrictors and venomous animals.

Also, a grown man couldn't remove the snake for obvious reasons. If you don't know what that reason is, you shouldn't own a large python. Never seen a snake immobilize a prey item, let go and bite again?
an 8 foot, emaciated snake??? Of course he could have removed it. It was only 8 foot. and emaciated. Hell, I could do that. I HAVE done that... Maybe let go and bite one more time to get a better grip....but 3... 4... 5 times? no they don't do that... they bite and hang on for dear life!!!!
