Do you know what his disability is? NO so why are you so quick to judge? I know a girl who is disability because she's dyslexic, but if she wanted to she could breed/sell snakes. Now while I don't know how that would affect her disability, she still can't get a regular job because of her being dyslexic. So don't be so quick to judge somebody.
Now while he was probably more then capable of working, he wanted extra cash on the side and it's pretty crappy that he even had illegal animals when he should of known better.
