If he still has his TCOLE license then he can likely find police work. There is a pecking order in TX LE and when you're no longer a 1st round draft pick with a larger agency you can often find LE work with constables offices and any number of smaller agencies that's willing to take someone elses problem child to put a warm body in a patrol car. That's why you have a lot of these gypsy cops floating around that go from one agency to another despite being horrible officers.
