This "is" criminal court .....
Only applies in criminal court. In civil court, it's proponderance of the evidence. In the court of the real world, neither apply much. If the NFL and/or the Falcons wanted to get rid of them, they probably already have enough to ditch him just on conduct unbecoming to the league or team. Many of Vicks sponsors have already either left, didn't renew, or suspended existing promotions until the dust settles.
My personal feelings is that Vick should take a voluntary unpaid leave of absence. With the case being heard on the Rocket Docket, I'd expect things to be done by the end of this upcoming season. There is no way Vick can help his defense as well as his team and the case will be a major distraction for both him and his teammates, even more so if he is trying to play at the same time. If he is acquitted, charges dropped, or a Duke Lacrosse type situation occurs, a leave of absence leaves the door open for his return. If he's convicted, then it can turn into a suspension and/or ban.
