Has it ever occured to you that maybe they weren't looking for you, and that you might have been caught in the wrong place at the wrong tikme, and end up just getting screwed because of it? The fact that they called in a copter because kids were smoking is complete bullshit. If they called in a copter (I'm not saying they didn't), it would probably be because they had reason to beleive that somebody who had done a much greater crime was in the area, and maybe they mistook you for that person... They may also not have told you this, because often police don't tell the public about these things so that the public don't flip a shit and get worried.
Also, not all cops are like that. One of my buddies and I were at a huge street jam/festival this one time, and we had some beers in our packs and my friend and his friend had a half-o each in their bags. A group of cops walked by as we were in a park waiting to meet up with some ppl, and they asked us to leave because they had been tipped off that a fight was going down in the park (the year before, huge brawls had happened and like 10 ppl got stabbed). Anyway, we gaught up, and the beers clanked. They asked us to stay and asked if they could search our bags. (In total we had a 24 between our bags). We weren't in the mood to jerk around, so we just said fuck it and let them search. They pulled us aside, and took out the beers and asked to see ID. We didn't have any, so they confiscated them. Then, one of them asked us "Is there anything else I should know about in these bags?". My buddy was just like "yeah" and both him and the other guy pulled out the weed. My friend was like "i'm not dealing, it's not dimed out or anything, it's just for me so pls don't press dealing charges". The cop then pulled me and him over, and was like "boys, the only reason I'm not going to press charges, is because you've been really cooporative tonight, and I frankly have to worry about bigger issues happening in the park. Sorry to have ruined your evening about the beer." And then he let us all go. To top it all off, when we left the park, we opened up the bags to check them, and both the bags of weed were still there! How sick was that?!?
So you can't honestly tell me that all cops are dicks, cuz I know they're not. They're out there for the greater good, and sometimes its their jobs to be dicks. It's not their fault, and they're just trying to help everybody out.
