The venue bars weapons from the site, even though Ohio is an open-carry state, according toThe Secret Service banned guns at the RNC convention in Tampa four years ago."This is a direct affront to the Second Amendment and puts all attendees at risk," the petition says, citing comments from the National Rifle Association opposing "gun-free zones" and pledges by the three Republican presidential candidates — including Ohio Gov. John Kasich — to eliminate them."Cleveland, Ohio is consistently ranked as one of the top 10 most-dangerous cities in America," the petition says, referencing a Forbes magazine story.
