If you don't talk to the authorities, they can't misconstrue or outright lie about anything you said.
Efforts to reach Weemer's attorney Paul Hackett were unsuccessful. But on a Web site established to help pay for Weemer's defense, Hackett wrote his client initially cooperated with investigators but is now "forced to rely on his constitutional privilege to remain silent."
Should have done that from the very beginning, even if innocent.
The whole thing snowballed. Weemer wanted to join the Secret Service and was given a polygraph test as part of the application process. During the test, Weemer was asked if he ever took part in an unlawful killing in Iraq. He responded, “Well, there was this one time in Fallujah...”
The Secret Service later called NCIS and agents showed up at the coffee shop where Weemer was working. The agents started out as if they were just shooting the breeze, and then things got more serious. Weemer was up to his eyeballs before he ever knew what hit him.
