Replying to Touble by the cops

sup ns. last night i was drinking in the dorms celebrating my friends birthday and it was pretty late so i was going to go back to my room and just go to sleep. on my way back, the cops stopped me and told me i was stumbling (which i wasn't) and they started to question me. being stupid, i answered there questions even though i clearly shouldn't have and i should have just remained silent.

then, they asked to see my id and then told me to empty my pockets. not knowing that my friend had put a beer in my pocket i thought i only had my phone and wallet so i showed them. they saw the beer, took it and then they radioed in something like some sort of code. after that they told me to walk with them for a minute, to make sure that i was ok.

i asked them if i was going to get in trouble with the school for this. they said i might get an email or something and taht was about it. they never wrote my name down or anything, they only got a quick chance to see my drivers license. they let me go and i went to my room and went to sleep...


how much trouble will i get in for this?
