As someone that just moved into Austin three weeks ago, I would NOT want to be a cop dealing with all the College kids here. It is, as others have put it, a VERY blue dot in a red state and the 18-30 crowd is a bit unruly (Google "austin 6th street violence"). The cop may have been a tool to her, I'll admit, but who the hell goes jogging without at least slipping an ID into their pocket?! If I get hit by a car/have a heart attack/whatever I want to make sure my next of kin is contacted ASAP at the very least...
More on topic with jaywalking, it really is that bad down here with all the joggers, bicycles/unicycles, skateboarders just acting like cars will always stop for them. I refuse to take my car downtown even if I only plan on having one drink, I just don't want to risk having my reflexes dulled and getting a dwi/dui because I clipped some drunk kid that stumbled into the road; $2 bus pass is always worth it to me.
