SWMBO and I were in Austin visiting her brother the day before this went down. We were a day and many miles removed from where the incident occurred, but it still creeped us out.
We also got a first-hand view of the homeless encampments, including the biggest one where 71 and I-35 cross. It's bad. The day before we were arrived there was an attempted broad-daylight car jacking. A homeless person was also killed when they passed out in the street and were run over (by a Texas DPS trooper, no less).
