What is the relationship between violence and sports? Psychologists say that there are many
reasons for violence at sports events．One is alcohol．Many fans drink a lot at games．When
people drink, they are more likely to do abnormal things．Psychologist Dennis Brock says,
"Quiet people become loud．Normally nonviolent people become destructive． "
David Sampson, a sports sociologist, says, "These are often celebratory riots- a large number
of very happy people mixed in with large amounts of alcohol．They don't often seem dangerous
in the beginning, but things get violent quickly． "
Another reason for violence at sports events is the crowd．When individuals are in a large
group of people, they can lose their sense of personal responsibility．Edward Hirt, a social
Psychologist, says that research shows that people do things in crowds that they would never
do alone．People in crowds feel anonymous - no one knows who they are．Crowds also
make people feel powerful．They stop making personal decisions．They just follow the crowd．
Social psychologists call this a "mob mentality".
Dave Zarifis, head of public safety says, "Some people don't even come to celebrate．They want
to drink hard and make trouble．Someone does something stupid, and it grows from there．You
get a mob mentality．People think it's OK to do almost anything．They think, 'There are so many
of us and not enough of them． '
Social psychologist Dr．Sharon Kennedy says that there are some things officials can do to prevent
violence．Making sure that an area is not overcrowded is very important．Officials should also think
of games as "big parties．" Then they will prepare differently．Kennedy says that in Great Britain they
are controlling the problem with cameras in all the stadiums．"When you know someone is watching,
you are much less likely to behave badly． "
