I get a little enraged when people are making excessive noise at the movies as well, but the end of Black Swan was definitely not worth shooting anyone over:
A man has been shot dead at a cinema in Latvia after a fellow movie-goer objected to the volume at which he was eating his popcorn. The assailant, 27, reportedly had a brief argument with the man, aged 43, who was sitting next to him during a screening of Black Swan in the Forum cinema, one of the largest in the city of Riga.
When the credits rolled, the younger man pulled out a legally registered firearm and shot the other man dead. Other audience members then phoned for the police and an ambulance. The younger man — a graduate of the police academy who holds a doctorate in law from the University of Latvia — waited to be arrested.
