Dallas' city government is corrupt beyond redemption. If money is available, they can forgive anything. But those whom they can't shake down, they destroy. Look at Sheriff Bowles... a BUSH supporter, and now out of office. District Attorney Bill Hill has been instrumental in the coverups of police and sheriff's dept. scandals, and Hill has been pivotal in dethroning Bowles.
Bill Hill is chief among those most corrupt, and I have no doubt that he and the most of Dallas' city government probably knew of Abdulquader long ago. With enough money, anything is possible in Dallas...
Well, Bowles was funneling department business to a good friend.
Can't do that, which is why he's gone.
