Doing some quick research online, I came across this:
1985: During VEISHEA weekend’s “Ash Bash,†cars were overturned and burned. 1988: Disturbances took place on three consecutive VEISHEA weekend nights. During the
Sunday morning riot, people in a crowd of approximately 5,000 threw bottles, bricks and rocks
and made a bonfire from furniture. Of the 45 people arrested, 25 were ISU students.
1992: During VEISHEA weekend, people in a large crowd (est. 8,000) threw rocks, cans and
bottles at police. Twenty-seven rioters were arrested and 47 were treated for injuries.
1994: During VEISHEA weekend, people in a large crowd threw cans, bottles and rocks at police.
A total of 20 people were arrested, 11 of whom were students.
1998: Prior to VEISHEA, students in a crowd of approximately 300 chanted profanities, set off
fireworks, and attempted to tear down a light pole in the Towers Residence Hall courtyard before
being dispersed by police. The event was viewed as a protest against the first “Dry VEISHEA.â€
1999: During a planned event three weeks before the second “Dry VEISHEA†and near the
anniversary of the previous Towers Residence Hall disturbance, students committed acts of
vandalism and chanted profanity in a crowd that moved from the Towers to The Knoll and then to
Jack Trice Stadium, stopping at various points on campus in between to rally loudly.
2000: Following an NCAA basketball victory participants damaged cars, pulled down light poles,
marched to The Knoll and then to Jack Trice Stadium, where they tried to pull a goal post down.
They then tore down pieces of fence and threw them in Lake Laverne.
2004: Rioters in a crowd of approximately 2,000 destroyed property in Campustown and three
objects at police. Police arrested 37 individuals, including 22 Iowa State University students and
three recent alumni.
There is a good bit more that isn't on here: People falling from buildings and being severly injured or dying and murder as well for starters.
