Ok attorney people, I'll have to quote JayZ here..."I may not have passed the bar, but I know a little bit..."
Burden of proof is on the prosecution. In a digital environment it's very difficult to prove who in fact posted those comments. You can track it to a computer, but you can't prove who was at that keyboard typing. Just going off of what was posted, you'd still have to convince a judge to get a search warrant to find an illegal substance. Even "IF" that happened, good luck finding anything to make it worth it or even get a conviction.
And IF I get convicted of anything I'd expect my fellow OCF'rs to stage a rigorous campaign to set me free...kind of like Nelson Mandela

I mean let's face it, if OJ can get acquitted I'm sure we can come up with something!
