Best to keep your mouth shut.
Little true story:
I have a buddy I lift with occasionally who also cycles, decent sized guy, muscularity, etc. Has the "look". There was this wiry, wormy guy that worked out at the gym, mid 20's, something slightly off about him....drugs maybe, not sure. He always wore workout sweats/pants. Always. Maybe he had chicken legs, maybe he got cold easy....I dunno. He tried starting conversations with my buddy and me about gear, hinting and insinuating.....like he would like to get a hold of some. We respectfully avoided the subject.
Saw him one day at one of squat racks and he bent down and started adjusting something on his ankle, lifted his pant leg up just enough and there was a nice ankle monitor attached. Who knows what his deal was.....he obviously had gotten in trouble and was being monitored. Maybe he had a snitch deal in place to try to link up LE to anyone and everyone who was committing crimes. Maybe the guy wasn't a snitch and legitimately was just trying to find a way to get gear and not be so damn skinny. I don't know and I don't want to find out.
There is an old mob saying:

They open their mouths.
