Mark, bill, and a host of other names used were all dea but now retired. The phone scam was reported to dea opr (internal affairs) as well as their office of security programs hundreds of times since 2008 that I know of. It's opr's responsibility to track that crap down. Security programs refused to address it and ordered all the division security folks to stand down on looking into it. Opr was both briefed on it and directed to handle it on numerous occasions, they did nothing. Never do anything productive, and are usually the parking location for trouble makers. Opr and security programs were given every phone number listed herein and obviously have the capability to run them to ground immediately. Heaven forbid they use a T3 to track badguys!
And oh, I forgot to mention that they called again today. I told the guy I wasn't falling for his scam and asked how he could sleep at night. He made all kinds of threats until I finally hung up on him. They just don't give up!
