Will Houston PD, DPS begin getting warrants for Stingray use now that feds require one?

Now that the US Justice Department and the Department of Homeland Security have begun requiring agents to obtain search warrants to use "Stingray" surveillance devices (fake-cell phone towers operated by police which trick your phone into routing calls through it), will Houston PD, Fort Worth PD, Texas DPS, and other Texas agencies we don't know about who own those devices start getting warrants, too?

Houston PD doesn't even tell local prosecutors when they use the device, much less seek warrants from a judge. But that approach now diverges significantly from federal practice. Can it be sustained?

The Texas Legislature this year failed to pass legislation by Rep. Duane Bohac and Sen. Craig Estes which would have installed a warrant requirement in state law. But there's an argument the Fourth Amendment to the US Constitution requires a warrant, anyway. So, with the feds backpedaling on the question in the face of numerous court challenges, Texas agencies should probably start seeking warrants, too, or else risk a federal benchslapping down the line.
