My question involves juvenile law in the State of: so I'm 17 and from California two days ago my brother and my cousin went for a run this other guy we don't really know asked if he could come with us we said sure, after walking/jogging to the riverbed which is open to the public we crossed a area which seems part of the riverbed once we got past that area the park rangers called my brother and cousin over I was further ahead and had headphones on so I couldn't hear them calling me but the park ranger sent my cousin to call me as soon as he did I went with the officer, I forgot to mention that I was carrying a small sport bag which belonged to the guy we barely know only thing that was in the bag that I knew of was my waterbottle and my brothers but the guy took off as soon as he saw me going to the officer he took some stuff from the bag and left the bag there with stuff still in it, so once the officers started talking to me they told me to pick up the bag and open it I said but its not mine and one officer said it dosent matter just open it then told me to give it to him which I did he pulled out a pair of jeans, my water bottle, and a black groceries bag that had stuff in it I don't know what was in it all he said is there was a pipe and crumbs of weed in a container, they never went after the guy that took off and told my brother and cousin to leave but then started asking me questions like why didn't I stop when they called me I said because I was listening to music and for some reason that got him mad then he asked if it wasn't my bag why was I carrying it I said the truth which was because the other guy that took off asked if we wanted to
