DPS uniforms, I think, which makes sense as the UT-Austin campus is State, not City property. It also means they may not be released by the Travis County DA.
Yes, besides which DPS having to take up slack around town due to what amounts to the functional collapse of the Austin Police Department. APD has shut down various task forces due to lack of personnel and investigators have to pull street patrol duty, which impacts attention to solving any major crimes. I know a kid who was wanting to move IN to Austin to be close to his job - told him he was nuts to want to do that, said to stay someplace in Williamson county, like Round Rock, Pflugerville instead for peace of mind.
