I did manage to finally find one story about TLS: Texas Law Shield protects gun owners | News - Home. Interesting timing, judging by the story byline timestamp. Also interesting that a successful use of TLS services were related, without any attribution of course. I also found the story itself fascinating:
"We've had a client in the back of the squad car call the emergency hotline as he was being taken to jail and our attorney worked with the client in the car ride and eventually the officer turned around and figured the member was correct and turned around and dropped him off," said Evans, offering one example of how the program helps.
Perhaps police procedures have changed, or are different in Texas, and please, any LEOs chime in here, but according to my family members who are cops, arrested folks don't generally get to use their cell phones in the back of the car. Especially on a weapons violation. Nor have have free hands available to operate them. I have also never, ever heard of an LEO changing his mind after an arrest and while driving to jail. It's not impossible of course, it just strikes me as let's say unusual.
