It's been years since I represented anyone on assault/family violence in Travis County, and even longer since I had a restricting breathing felony case, but when I did this kind of work, I could present the assistant D.A. handling the case with an affidavit of non-prosecution, which is generally a "I overstated the severity of the event, I don't want the defendant prosecuted, he's really a swell guy" affidavit from the alleged victim, and I would be told that the policy of the D.A.'s office was to move the case to trial and if the victim refused to cooperate and testify against the defendant, then, and only then, would the case be dismissed. This was more than 5 years ago, but I doubt any D.A. is going to risk losing an election because the defendant goes back and chokes the shit out of the victim after the case is summarily dismissed. It would likely take months if not a year for the case to get to trial. I don't think there is any way you will ever see Chris Beard coach the Longhorns ever again. I don't see the university waiting for a year when the outcome could be really embarrasing.
I'm sure there are some lawyers on the board who actively doing criminal defense in Travis and if things are different, please correct me.
