Some nice follow-up work here.
Short answer: The DEA says the man in the photo is indeed a DEA agent, and not a Blackwater employee They say they asked the L.A. Times to blur his face because he sometimes works undercover. The Times doesn’t alter photos, so they just pulled down the picture, instead. Lingering questions include why a DEA agent was advertising for Blackwater during a high-profile drug raid on a med-mal clinic, and why an undercover officer would participate in such a high-profile raid, and then expose himself in public like that in the first place. Surely they knew there would be cameras there.
Make of all this what you will.
Here’s an assignment: Someone with more time than I have at the moment should file a FOIA to see exactly what sorts of drug interdiction contracts Blackwater actually has with the federal government. I know they’re doing quite a bit overseas. It would be interesting to see what they’re doing domestically.
