I am not familiar with Pacman's recent run in with the law, so I can't and won't pass judgement.
The NFL is a business. Jerry Jones is in the business of making money and to the best of his abilities, trying to field a great product.
Adam Jones would be a definate upgrade over the unknowns we have at Cornerback in Dallas.
Dallas has also been a place of sanctuary, where guys like Keyshawn Johnson, Tank Jonhnson and Terrell Owens were able to seemingly turn over a new leaf, at least in the eyes of fans who viewed their acquisition with a questionable smirk.
Does values and ethics have a place in Pro Football? Yep, they sure do. However, if as GM Jerry Jones can reach out to Pacman Jones and allow him to turn his life around, I would't be too oppose to that either.
