Li'l story about tonight... tl;dr at bottom
So I was just waitin' on the lake for my boy so we could have a quick burn session. I had the blunt stashed under a trash can on the path, right. Me and another dude are waitin' for like 5min and see someone finally walk up the path so I go to pick up the J. The second I bend over and grab it I get hit with a flashlight, dutch smooth in my hand. We think it's our boy hittin' us with a cell phone flashlight, so he calls him a faggot and to turn that shit off. Turns out it's a cop.
He asks us what we're doin', yadda yadda, and asks for IDs. As I pull out my license I slide the J in my back pocket. He runs our names, asks why grown men are on the lake at night and all that shit. After we bullshit him a little bit he tells me to put my hands on my head and turn around, goes to search me. I asked why, and then he asked permission to search and I told him I'd prefer that he didn't. He went for the patdown instead, missed the blunt and asked us where our 4/20 weed was at. We bullshitted around for a few minutes and he told us go home, tellin' me to throw the bowl in my pocket away. I laughed, show him I had no bowl and walked home, smoking my J right as the Xanax started kicking in.
TL;DR Don't ever give consent to search to the police. Without probable cause or consent, they can't do a god damn thing that'll hold up in court (or the street if you have a cool cop)
