Somehow I'd missed this bill during the regular session, but if I'd known about it I might have gone to testify on its behalf. As Grits mentioned earlier, on the company's website, "the company claims the authority to "Apprehend and arrest suspects for crimes against you or your property," though of course private security do not have 'arrest' powers." Further, a sign they provide "free" to customers declares that, "All vehicles and persons on this property are subject to being stopped and questioned," and that "All persons on this property are subject to search as this is private property." (Emphasis in original.) Their client list includes apartment complexes and homeowners associations, so if true, such authority would presumably include visitors going to and from private residences.
On the Texas State Troopers Association website in response to Grits' post, someone suggested readers lookup "State Tactical" out of Houston, so I did, and their vehicles and uniforms look even more cop-like, complete with flashing blue lights on top of their cars, armed with tasers, shotguns, and even semi-automatic weapons. Check it out for yourself:
I don't know if it will be possible for Harper-Brown to tack her bill onto anything moving that's allowed under Governor Perry's various "calls" - perhaps the Sanctuary Cities bill may be a possibility - but I'm increasingly convinced this is a significant issue going forward.
