You know, I think Lithium does that just to get a rise out of the adults, and it works. I don't agree with the "pig" crap either, and sometime Lithium acts like a moron, but it would be best to let him do his thing. Maybe, God forbid, he will need the help of the "pigs" and then he will learn a lesson from it. Yes, there are bad cops, but more good cops, who joined to protect and serve.
If ya wouldn't have been breaking the law, no matter how small, you wouldn't have gotten caught. Simple. Grow up. Let's see you call them "pigs" next time somebody robs you, hits your car, or whatever might happen.
