Nobody comes in my house claiming to be law enforcement, including secret service, without showing some credentials first. I too was a Marine and would not put up with this bullying. Show me something, then we can talk.
Responding to Jessica's questions, the agents would not identify themselves by name,...
These were not Secret Service agents. Genuine agents would have been required to identify themselves. They did not comport themselves in the professional manner of real agents.
Also, getting a copy if the lady's cell phone conversation is easy to do. So is verifying which phone from the phone bank placed that call, and who was on duty at that time making those calls. These guys were thugs impersonating Secret Service agents, which is, I am certain, a serious federal crime.
If we had a real Justice Department, these guys and that phone operation would be shut down pending an investigation and possible prosecution. Unfortunately, we haven't had a "real" Justice Department for a long, long time...
