Here in Texas, state troopers, any number of different Fed agencies, Texas Rangers, if something big happened, National guard, but, I’ve never seen the use of active duty military.
This has some sort of stink to it.
The vaunted Texas Rangers are an INVESTIGATORY branch of the TX DPS. They are not utilized as "front line" LEOs, I've worked with them quite a few times during 31 years as a state LEO. People have watched too much "Walker Texas Ranger" and Rangers don't run around with five-day beards either, always clean shaven and professional looking, shirt, tie, hat, like they should be (very strict dress code and professional pride combined).
Things go in cycles, I've seen two attempts to disband the Rangers, another one is being talked about as I write this. Probably won't happen but don't think that it can't. Many people have lost the importance of keeping traditions which engender morale and efficiency.
