Has anyone ever been contacted by an intelligence agency asking them about suspicious activity (that they think you conducted?)

What happened when you tried to apply/renew for TTP status?

as someone adjacent to a university, especially at the graduate level in an engineering program, we get a lot of whispers on whether someone is this, or that, and a bunch of plainclothes do roam some of our halls and it's pretty obvious who they are...and i guess my name was shouted out by someone a few years ago after an arrest was made

no charges, just intense questioning until (maybe) they realized how ridiculous it would be for me to have done the things they said i'd done

(i'm innocent i swear) but now that i'm getting towards NEXUS/GE renewal, i'm wondering if i should look into following up with that one 5EY agency that interrogated me that one time to see if i'm in the clear?
