re: Cop stands up to gun nut in Texas.

If you are walking around an urban setting with a rifle you should be stopped and checked out.

Only time I ever open carried was in the weeks after Katrina and I kept my State drivers license in a lanyard around my neck too.
I didn't want to get shot for carrying, there was a ton of ID checks at that time, especially when going through checkpoints manned by NY state police and other yankee cops.
