FBI documents reveal Las Vegas shooter's anger towards casinos as possible motive.

Newly released FBI documents reveal that Stephen Paddock, the alleged gunman in the 2017 Las Vegas mass shooting, was angry at casinos. Paddock was a prolific video poker player who frequented several casinos in Nevada and had a bankroll of between $2 million and $3 million. According to a fellow gambler, Paddock was upset at the way casinos were treating him and other high rollers. The FBI notes that casinos changed their approach about three years ago and started banning high rollers from certain events, hotels, and sometimes certain casinos. The 2019 FBI report found "no clear single motivating factor" for why Paddock opened fire on a country music festival, but added that he wanted to kill himself and sought infamy by murdering others.
