Anyone venturing into a 3.3-square-mile event zone" surrounding next month's Republican National Convention will be prohibited from carrying tennis balls, tape, rope, bike locks, sleeping bags, or any object they could stand on to rise above the crowd and speak. But if they have a license, they'll be permitted to openly carry real guns, including assault weapons. The restrictions imposed on the large event zone drawn around Cleveland's Quicken Loans Arena ... have earned the city a lawsuit filed by the ACLU of Ohio and widespread criticism. "It's the first time I've gone to a protest where there's been so much talk of guns and the fact that people can carry them legally," said [activist] John Penley. "They throw pro- and anti-Trump protesters together, and throw in the fact that maybe people will be carrying weapons. It seems like what they want to do is increase the chances for conflict." Cleveland received a $50 million federal grant to gear up for the RNC. The city has obtained ... 10,000 sets of flex cuffs; "nonlethal munitions" like bean bag pellets; pepper spray; 2,000 sets of riot gear; 2,000 retractable steel batons; 3.7 miles' worth of steel barriers; as well as ... video surveillance equipment, laptops, night vision devices, and 16 Pointer Illuminator Aiming Lasers, which a technology retailer describes as being used for "night direct-fire aiming and illumination." The convention center itself is under the control of the Secret Service, which has imposed a separate set of restrictions, including a ban on weapons.
