I can assure you, even if that was his job/agreement/duty(which apparently we now know it wasn't), those possibilities crept into some part of Nick's mind at some point.
Regarding Nick, you're right, he was released through no fault of his own. The reason he was put back in jail was, however, no one's fault but his own for not abiding by the terms of his release. I have no problem with the bar owner giving the guy a job. The fact that Nick is an RSO isn't his only problem. The fact that he's an RSO that was the last person known to be with Kelli creates a problem for him. If he was an RSO that remained at the bar and everyone vouched for him and someone else was known to have taken Kelli home, my guess is that not as much attention would be drawn to Nick. I would also suggest that LE's insistence that this case centers around Nick indicates that LE may have even more information than us that leads them to believe that.
I'm sure there are other "bad" characters at the bar, no different than anywhere else. Probably even some that have criminal records. I would also suggest that they have all been looked into by LE. I understand what you're saying. I hope and don't want LE to have tunnel vision when it comes to Nick, but at the same time there is no way I want them to take their eyes off of him either.
