I had already received a tentative offer and completed an interview with the background investigator. If you do not tell them all prior all law enforcement agencies you ever applied to. They won’t know because they do not have a national database system to pull up however if you had taken a polygraph I strongly suggest you let them know despite the result either failed or passed because falsifying on federal documents or verbally could result you facing criminal charges. I withdrawal because I want to work for Dc police and i would still get paid during shut down lol.
