WHAT THE FUCK IS WRONG WITH YOU?
I mean really.. You do understand that the only people who would witness Vick at a dogfight are OTHER PEOPLE AT A DOGFIGHT, right? You also understand that most witnesses are deemed credible, and their testimony is just as damaging as any physical evidence, right?
Murderers and rapists would be considered scum and somewhat unreliable, but guess what phil.. A lot of murderers and rapists have turned and snitched people out for things, and those people were convicted. You know why? Because chances are they were both engaging in the same activity and are more likely to witness the event then anybody else.
You wanna make witnesses seem like they are not credible.. Just give it a rest.
