Don't let the name fool I don't smoke weed I barely drink I wasn't doing anything illegal and I have no criminal record I'm always obeying the law I just felt that they didn't have a reason to open the doors and they also wouldn't give me a reason for pulling me over

I was pulled over for no reason and the police opened my car doors without a reason and asked all my passangers idenity... Did they push their boundaries or do they have grounds to inspect a vehicle?
