For those questioning what RM's "hat" type is.

He, along with the entire FBI Anti-Terror Group were in Monterrey, Ca. for a 'retreat'. They were all scheduled to fly back on commercial air.

Sounds like if you wanted to marginalize your best and most experienced team of investigators this is how you go about doing it.

As an anecdote I was in Monterrey, specifically Laguna Seca and I can tell you it was absolutely CRAWLING with spooks on vacation. Was an ALMS race at Laguna the prior weekend and several were there. The security for a normal race weekend was off the charts.
