As stated before - cops can anwer any way they want - no defence. They can tell you lies, incriminate themselves, etc - you have no defence if you sell.
Safest bet - tell people to fuck off. I hate going up to someone at a club to have a chat and before you even get "hello" in, the old "got any pills mate?" line. I say, "well at least you're straight to business... but no."
Don't people figure if you waste two minutes of your time with them, then they are more likely to sell to you?
Cops may confiscate and keep - but they will nick you. You may have had 12 pills on you, but they only report 3 when u get your call from the cop hop - you're a dick if you complain and up your charge - so you just accept it and let the cops take your pills.
Don't worry - the pills they confiscate go to their buddies to sell within the rave, making a little retirement money, so they do get eaten
. I mean, if i was a cop, shit i'd be tempted to do it.
I seriously doubt the "cops being fucked up on dugs stories". If they are in uniform, you are a loon if you think they are pilling, and you most probably will get busted selling or something equally as silly.
