Minor in Possession (MIP)
For persons under 21 to have any container of alcohol in any public place or any place open to the public (Business and Professions Code 25662). To be under the influence of alcohol in a public place and unable to exercise care for one’s own safety or that of others (Cal. Penal Code 647(f)).
So, let's say Sarah, a frosh, is at a party and she's drinking out of a red cup. A Public Safety officer enters the party. She's cool, it's her first and only beer. She doesn't appear to be under the influence and clearly can take care of herself. So far, so good.
Her friend, Zach, is also drinking beer out of a red cup, sees the officer, startles because he's afraid he'll get in trouble, and runs outside. The officer gets concerned about Zach's bolting act, so he follows him outside.
Uh, oh - MIP citation likely. He's a monior who is drinking and it doesn't help that he was actively avoiding the officers. They're here to help our students, not just to throw out citations.
Now, let's say their housemate Jessie, is weaving and wobbling around outside to get some much needed air. The Officer notices her because she's obviously staggering around. It's questionable whether or not she can take care of her own safety. Uh, oh - DIP, and maybe MIP, citation is likely. Because she may not be able to care for her own safety, she could be taken to the "drunk tank" in Santa Clara County jail to sober up. In that case, her residence staff will be notified. A court date might be set to address her MIP/DIP.
