My question involves juvenile law in the State of: Arizona
Ok so the other day me and my friends went out for one night with the intention to smoke. Us 3 told each other's parents that we were going to eachother's houses, so we slept in our friends car who is 17 turning 18 in october, I am 16 however, and my other friend didn't get charges. Anyways, we slept in his car in this usual place we always go that is secluded from houses but is WITHIN a neighborhood, a perfect spot for anyone to park if they wished.
That morning I woke up with a knocking on the window and it was an Officer, instantly I rolled down the window and asked "Goodmorning officer" and he asked me what we were doing here, and I told him that we each told eachother's parents we were spending the night at eachothers house so we slept in the car after hanging out one night. Then, 3 police pulled up and we were allll getting questioned. My officer told me to wait while he and another officer walked over to the vehicle with both doors open and began looking in, stuck his head in and looked around but didn't touch anything, then out of no where, and I didn't witness them converse to say it was probable cause or anything, and he opened the middle console where our pipe, grinder, and some weed in the grinder was. Our friend who owned the car was then put in cuffs and they began to search the car. My backpack had a jar that had about 5.5 grams which we bought off this guy at a party who tried to get rid of it quick, but they were all individually packaged. I took the blame for that, but they didn't find a scale, other baggies, or any money except like one dollar in my wallet.
The officer I had, filed it as possession and said good thing we didn't find a wad of cash or anything like that. He agreed that marijuana laws are dumb. He said though that the courts may view it different.
My Questions:
Based on this info, is there a strong chance I can just get possession because I have never sold, and don't intend to do so and was just a wrong place and timing type thing.
What type of punishment am I looking at.
Where will my friend go after he is charged when he turns 18, for charges of Possession and Paraphanilia.
Thank you so much!
