The Raiders did not respond to a request for comment.
Lanier said the incidents were troubling, but not inherent to Las Vegas.
“I think the instances that did occur there are unfortunate, but unfortunately those circumstances can happen anywhere,” Lanier said in an interview.
The N.F.L. for decades avoided Las Vegas, mainly because of Nevada’s legalized gambling on sports. In 2007, the league suspended cornerback Adam Jones for a season for misbehavior that included a role in a fight at a Las Vegas strip club during the N.B.A.’s All-Star weekend. Three people were shot, and Jones was given a year of probation as part of a plea agreement.
In 2017, team owners approved the Raiders’ relocation from Oakland, Calif., after its failed bid to return to Los Angeles. The league embraced Las Vegas even more after a U.S. Supreme Court ruling in 2018 that struck down a ban on commercialized sports betting in most states. The league awarded the city the draft for this year and the Super Bowl in 2024.
Still, N.F.L. players and personnel are prohibited from entering sports books during the season, except to briefly pass through to access approved areas, such as hotel rooms. League employees who are not players are not allowed to bet on sports at all, while players are allowed to bet on games in other leagues. The N.F.L. Players Association, the union that represents the players, also offers a prearranged driving service to discourage drunken driving.
According to a league spokesman, 32 N.F.L. players were arrested in 2021, and there are more than 1,600 active N.F.L. players on rosters.
Lanier said that because only a small percentage of players had been arrested, she did not think it was necessary to regulate athletes or employees differently from one city to another because of varied entertainment offerings.
