LAS VEGAS (AP) — Las Vegas’ tourism sector is bracing for changes in the aftermath of the massacre that killed 58 people at an outdoor music festival. Analysts who closely track the finances of the city’s casino companies say Las Vegas will see a short-term dip in visitors in response to the shooting. Casinos and police may have to impose new security measures after gunman Stephen Paddock brought more than 20 rifles into his hotel room and drove a car filled with explosives into the parking garage.
