It was not a fed investigation. Sheriff's office was investigating sex with a minor for weeks and they asked DHS for an assist.
Another thought,and perhaps the reason for the DHS assist,is that it is possible the pilot was armed,an FFDO, which is a TSA/DHS program.
But was he?
And if he was, why go in when he would be armed? What was SO important to get him right then and there?
Everyone seems to ignore the question I have- why go in when you know you have to gear up? Why take that risk when you can wait for a lower-risk opportunity? LE wants to puff up and show dominance at any chance they get.
I don't hold very many LE folks in high regard. Most of them that I know are folks who wouldn't be allowed in the military because they're too stupid, too fat, or too sexist and racist. It's a low-paying job that attracts the bottom of the barrel, yet they want to be called "Officers".
The true professionals I know want out, or got out, to do other things that pay better.
The stories I hear from some LE folks who are part-timers here make me really glad that I won the birth lottery.
