So one night I decide to hit my friend up and smoke a blunt with him and my girlfriend. He tells me to hit up our mutual drug dealer friend and he will pay for it. So all three of us travel down to his house after I texted him to make sure he had the green. I roll up and he comes outside and hands me the green while I'm in my car in his driveway. We drive not even a mile down the road to go to a gas station to get a blunt shell and we get pulled over right in front of my buddy's house. I automatically give the gram to my girlfriend who puts it in her bra. Before I go more into detail the funny thing is that this under cover car comes out of nowhere and doesn't even have any head lights on but he was following me the whole time so I didn't see him. So the officer comes up my window and tells me that my tag plate is not illuminated and that's why he pulled me over. He asked for my Id and registration. I give him those things and then he makes me step out of the car and asks me if he can search the car. I told him no but he says that he will just run a dog by to smell for drugs. He also asked if I had anything illegal but I said no. So he pulls my gf and friend out to run the dog by and searches my friend an checks only my girlfriends jacket pocket. We were pretty much in the clear because I had nothing else illegal in the car but my girlfriend freaked out because of the dog and dropped the mj on the ground next to her. One of the other officers saw what happened and arrested her. He said she was tampering with evidence. They then ask me and my buddy who weed it is and we say no ones. well he automatically arrests me and says he is charging me with simple possession. Now I he screwed up because before he questioned us he didn't read me my rights. So that's the first screw up. Then he screwed up again cause he never fully searched my gf so how could she be tampering with evidence if she never got searched correctly and the evidence was in plain sight and wasn't hard to find. Then he lets my friend go without even searching his backpack. I also never admitted to owning the weed nor was it ever in my possession. so someone look at this and tell me if this shall be a hard case or not because these are all the facts.
