All this has happened at our school and worse. The Friday before classes started first year, people were reserving seats and the administration had to put a deadline for the earliest you could do that in susequent years.
I've nicely asked 2 people to shut up during class and was rewarded with a door being pulled shut on me by one and the other brought the loudest food possible into class and shared with the class.
Throw in the 3 dui convictions and the 8 other drunk drivers that havn't been caught yet, plus the cheating, like the harboring of a stolen test that 5 students had that blew the curve (11 studetns got D's) and resulted in one student D-ing out, and the vet school classmates are probably the biggest disppointment of my life.
The administration doesn't have the guts to do anything; they've caught cheaters before and the one dude I know they caught keyed the professors car and another student caught him in the act and they still let him graduate. He's actually a practicing vet now! Its BS, but thats what happens when you base admissions 75-90% on grades and GRE scores instead of work history, letters of rec, and interview. Cheaters get good grades, duh....
