While 1 rape is too many, its also not unheard of at events like this anywhere in the world depending on the venue, security etc. Gotta figure, drugs, alcohol and thousands of young people are a potent mix.
There will be many mostly minor crimes reported after the Faster Horses Music Festival at Michigan Speedway later this month. There will be drugs, alcohol, young people and camping so the potential exists for crime and stupidity. That's not to suggest that people shouldn't go to these things, only that they be vigilant and stay sober enough to keep their wits about them.
