Texas Department of Public Safety, aka State Troopers, have always worn cowboy hats. I wore a cowboy hat when I worked for a sheriffs department, and they were part of department uniform issue a a police department i worked at. I still wear one every day, and the sheriffs department here all wear cowboy hats.
Its what we do down here.

Got a new silver belly every fall, and a new straw every spring, department furnished.
