Cleveland's police chief says the law enforcement officials tasked with overseeing the security of the city during the four-day Republican National Convention are prepared for "anything and everything."
Chief Calvin Williams said the force has gone through the "what if" scenarios, the "table top" exercises — security sessions discussing the roles, responsibilities and responses to any given situation — and ultimately "have planned for everything that can and will happen."
Those confident assertions will be put to the test starting Sunday as thousands pour into the city for the convention, and thousands more, representing various causes, prepare to march and demonstrate.
The Republican National Convention, at Cleveland`s Quicken Loans Arena, brings together delegates over four days from across the country to vote on the party platform, hammer out party rules and officially choose the party's presidential and vice-presidential candidate. It starts Monday and runs for four days.
Conventions have often been the scene of violent protest and that concern has been amplified by the tension across the U.S. in the wake of high-profile police shootings of black men, which have led to demonstrations and clashes with police.
Security issues have also been heightened following the shooting of five police officers in Dallas by a sniper and the recent attack in Nice, where more than 80 people were killed when a man driving a truck barrelled down a crowded street.
'Concerned about the possibility of violence'
There is also worry that Donald Trump supporters and protesters, who have clashed at other rallies, could precipitate more violence.
"I am concerned about the prospect of demonstrations getting out of hand," Homeland Security Secretary Jeh Johnson told the House homeland security committee this week. "I am concerned about the possibility of violence."
FBI Director James Comey, speaking at that same hearing, added that there is always concern that an event like this will attract people from across "a spectrum of radical groups."
Along with local officials, dozens of federal agencies — including the U.S. Secret Service, the Department of Homeland Security and the FBI — have been and continue to be involved in security detail.
The city was given a $50-million grant to boost security specifically for the Republican convention. Officials have been wary to provide information on security, but anywhere between 4,000 to 5,000 state and local law enforcement officers will be on hand for the event. Officers have undergone hours of comprehensive training, Williams said.
Extra equipment includes 2,000 sets of riot gear with body armour and batons, 2,500 steel barriers and 16 police motorcycles, CNN reported. Meanwhile, security cameras have been placed throughout the city.
"Trust me. There will be enough video coverage both on the ground and in the sky," Williams told reporters.
Around 3,000 personnel, including members from the U.S. Secret Service, Homeland Security and the Coast Guard, are dedicated to the security of the convention itself, Johnson said.
On Friday, officials set up concrete traffic dividers and tall metal fences around the convention site, propelled by fresh urgency in the wake of the Nice attack.
Security experts said that the U.S. Secret Service and other law enforcement agencies have viewed vehicles as a potential threat since early in their 18 months of planning for the convention.
A 4.4-square-kilometre event zone has been established in downtown Cleveland, with protest groups being assigned permits and being limited to certain areas. Some who never sought a permit, however, have suggested they may demonstrate in other areas.
No tennis balls, but guns OK
Security officials drew up a list of prohibited items within the event zone that include items as diverse as water and pellet guns, knives, sledgehammers, ladders, coolers and ice chests, canned goods, umbrellas with metal tips and tennis balls.
But Ohio is an "open carry" state, meaning gun-owners will be able to carry firearms, except within the security perimeter that surrounds the convention venue, dubbed "The Q."
This has raised some concerns, as certain groups, like the Oath Keepers, have suggested they may come armed.
