As an adult we deserve equality and we deserve the right to share equal liberties.

#2 Many people on college campuses drink alcoholic beverages and if they were to need medical attention they wouldn't have to make the choice of whether to go to jail or live.
#3 free up jail space

NOTHING underage drinking is unpreventable, the least we can do is make it safer by educating and offering help
