I'd have to concur. As much as I love animals I can't equate animal and human life. This guy may be a loser, but does it serve society to lock him up for two years (at an expense of about $25,000 per year)? A few months, max, would have gotten the message across just as effectively.
A few months wouldn't phase this guy. This guy has a long history of dealing with law enforcement. By this point, he can do two months standing on his head.
