How do you explain the fact that only a third of the folks arrested had prior criminal records?
Probably an overly zealous LEO reaction in an attempt to prove how hard-ass the Waco PD - and whole criminal justice infrastructure - are. I'm sure a lot of people with no criminal intent got swept up, and they may well be judged not guilty in the eyes of the law, but I probably wouldn't use the term innocent.
It's hard to feign innocence at the same time you're surprised that only 1/3 of the people you're hanging out with have criminal records.
