Quite simple:
(1) They broke the law.
(2) They lied about breaking the law afterwards.
(3) We have rules governing evidence in our courts, and their lawbreaking invalidated the evidence against the drugrunner. He would be in prison now if the agents hadn't compromised the investigation with their illegal activity.
(4) The drugrunner - like anyone else in the world - has a right to sue anyone in a US civil court.
His suit completely irrelevant to the issue. A random guy living in Kazakhstan whom you have never met could theoretically sue you in civil court tomorrow for any number of made-up reasons as long as he filed a complaint - the drugrunner's suit has nothing to do with the President or the DOJ.
Amazing. Two BP agenst DOING THEIR JOB shoot a drug runner in the derriere and YOU take the drug-runner’s side! :o
That’s the mindset that trial lawyers look for during voir dire...
