just ask him i'f he's a cop. my homie got arrested selling drugs to an undercover cop who he thought was his homeboy for about 2-3 years. the guy smoked weed, sniffed coke, smoked crack, everything. like i said 2-3 years undercover and he got busted not too long ago. anyways that was a buyer tho. HMM it's really up to you to determin i'f you think he's a cop, it's a simple guess and you better hope it's the right one. i've dealt with ALOT of cops and still i cant ever really tell 100% i'f someone is undercover or not. i usually go with my gut when it comes to strangers..OH and undercover cops usually try and catch BIG time dealers or buyers..if the guy asked something like "WANNA BUY A POUND OF SOME HERB or WHERE CAN I BUY A POUND/KILO or w/e it's usually a DEF sign that he might be a cop.. LIKE THE RULES SAY NEVER TRUST STRANGERS my guess was you should have bought it..but dont get friendly with him either..

to try and answer your questions, ask him i'f he's a cop(dont always trust this though, they dont have to tell you they are if they are but its worth a try). hmm check the way he dresses, usually undercover cops try and dress like dealers and they overdue it. listen to the way he talks.. listen to key words..get update on the recent drug slang.. for example( hey miss want to be some marijuana DEF sign of a cop; (buyer) yeah i need some crack/rocks DEF sign of a cop... the way they ask you can sometimes give it away..if u are streetwise that is... thats my 2 cents though
