Guns N' Roses' 2002 tour, their first in nine years, got off to a rough start when mechanical problems kept Axl Rose's flight from reaching Vancouver in time for the trek's opening night.

According to MTV, the show was cancelled with Rose literally in the air on the way to the city. Fans did not take kindly to the news, throwing bottles and rocks and breaking the venue's glass doors. Police armed with batons and attack dogs entered the fray -- by some accounts, using too much force -- leaving some of the rioters bloody, bruised and dealing with the after-effects of pepper spray, as Rose's bandmates sat backstage, completely unaware of the chaos around them.
