Stupid is as stupid does Sir!
Technically he hasn't pleaded anything yet because he hasn't gone to trial. He can plead the 1st on the flag burning (sorry -- desecrating a venerated object) but he's not going anywhere on the other charges of theft, public intox, and underage drinking, evading arrest and the rest. It will be interesting to watch how the desecration charge plays out.
I'm surprised he didn't get a big time country ass whipping for torching the stars and stripes. He was certainly ripe for it.
And I agree with Mal on this... these parents are further proof that a parental certification is required before you are permitted to procreate.
*ducks and runs for cover on that note*
