The National Football League has been slapped with a lawsuit by two Minnesota law enforcement organizations challenging its authority to prohibit off-duty officers from bringing guns into stadiums, reports the Star Tribune .
Since 2003, state law has allowed licensed peace officers to carry weapons in private establishments, even when signs banning guns are posted. But in September, the NFL alerted team owners that it was instituting a new policy forbidding anyone other than on-duty officers and private security personnel working its games to carry weapons in stadiums.
