Today I left my house to go visit my mom. She came and picked me up and grabbed me, and I left my car at my brothers (I live there). It was parked on the street. I later got a call that someone had called in my car as "suspicious" and called the police. The reasoning for this is probably because it has several boxes in the back (I'm helping move some things for my mom into her new place). It has been parked in that same spot every day for the last year. The police called me after searching it and had confiscated the keys and wanted my mom to come pick them up (the car is in her name). They found a corncob pipe and called my brother who I live with talking about how I had "drug paraphernalia" (it was only used with pipe tobacco, they scraped it and I offered to drop for them) and telling him he needed to get in contact with my mom to have her come pick up the keys. 

Basically, I'm taken aback that they went through the car. Though it was unlocked, they essentially entered my (my mother's by title) vehicle and stole her keys. Am I in the wrong, or did they really have no right to be in there and take my keys?
<bot>: Cops entered my unlocked car without permission, took the keys, and then called me to get them back. Did they have the right to?
