Amazing how much things have changed over the past couple of decades....the person who reports illegal activity in a college dorm (where all types of smoking is prohibited) is the 'dick', while the persons who committed the crime, violated dorm rules, and violated campus policy are apparently given a pass because 'nearly everyone else in college does it'.
In all likelihood, a student near Cheech & Chong's room reported the smell of pot to the RA, and the RA reported it to campus police. The 'dick' who reported it to the RA may have never intended to get the police involved --- just wanted to report it to the RA and see if it could be handled internally without incident. It may sound strange to some, but maybe the 'dick' who reported the illegal activity was actually trying to study for class instead of smoke weed 'like everybody else'
