Mackay, the Texas Rangers are indeed used many times here to conduct an investigation where no bias can be brought up at a later date.
Most agencies refer to them because of that. From past experience with them, they sure don't mind calling a spade a spade.
Much, much better than an in house HPD investigation where questions of coverup already exist. HPD shoudn't be investigating themselves under any circumstances in this. I'd trust the FBI even less.
