Authorities say they are now taking steps to make sure a Dallas-style nightmare doesn't erupt in Cleveland, where "open-carry" — meaning anyone is allowed to have a gun in public — is legal.
Following the events in Dallas, a rep for the Secret Service said: "A tragedy like that definitely impacts our planning."
The convention will be held at the city's Quicken Loans Arena, and a super-strict "secure zone," where unauthorized weapons are forbidden, has been established by the Secret Service.
Cleveland FBI agent Stephen Anthony told Inside Edition: "This kind of built-in contingency to be flexable, nimble, be able to react, is what I think the folks have worked so hard to be ready for."
Texas also has an open-carry law and police say it contributed to the confusion during the shootings in Dallas Thursday, causing one man to be falsely identified as the gunman because he had a rifle slung over his shoulder. He turned out to be a law-abiding protester exercising his right to carry a weapon.
At the Cleveland Armory Gun Store, Inside Edition spoke with owner Todd Karam about the situation.
"You can open-carry in the state of Ohio, as long as you are not touching your gun with an intent to use it," he said.
