On campus, most incidents are dealt with by campus security aides or residence hall staff. Some authorities will be more lenient than others, so it's almost impossible to make any categorical assumptions about the repercussions of breaking campus policies. Keep in mind, however, that campus security and hall staff can always involve the police if a student is breaking a law—and they most likely will. However, on the whole, University Police Services is more concerned with drunk drivers and public disturbances than with smaller issues on campus. In town or on the streets, you're only likely to be stopped if you're causing a disturbance or are very obviously intoxicated. Most students are smarter than that, and can last their entire undergraduate career without having a run-in with security or the police.
In the residence halls, quiet hours are enforced, although there are seldom serious consequences. Certain halls allow "of age" residents to possess alcohol, but its discovery in other dorms will lead to negative outcomes for all involved. However, only students causing notable disturbances are likely to be discovered. In general, there are relatively few incidents on the Kent State campus. If you do get into trouble, police and security personnel are generally understanding, and they'll most likely respect you if you respect them. However, students who are smart about the things they do and the ways that they go about doing them should have no problems.
