Cleveland is bloating with thousands of well-dressed visitors as Republican National Convention delegates arrive for Donald Trump’s weeklong coronation. But how history remembers the event may well be dictated on the street beyond checkpoints crowded with donors and those they woo.

Local officials and visible protest leaders are asking for calm during the presidential nomination festivities, but what actually happens is anyone’s guess following violent clashes this year at Trump rallies across the country.

“We’re asking everyone who comes to town to respect our city,” says Larry Bresler, executive director of Organize Ohio, one of the most prominent progressive groups coordinating protest activities. “I’m cautiously optimistic.”

Authorities armed to the teeth and covered by a $50 million insurance policy will supervise many city-permitted protest marches, speeches and rallies, some allowed after a federal judge found restrictive permit rules were likely unconstitutional.

Organize Ohio and allied groups will hold a “march for economic justice” on Monday, aiming for 5,000 participants. The parade route east of the convention center is a special one, owing to the American Civil Liberties Union's successful First Amendment lawsuit, also filed on behalf of the coalition Citizens for Trump.

Citizens for Trump is booked for the first march Monday on an official parade route south of the convention venue and will host a concurrent pro-Trump "unity rally" in Settlers Landing Park along the Cuyahoga River.

The city has approved large anti-Trump marches expecting about 5,000 people and put on by the Stand Together Against Trump organizing group on Tuesday and Thursday along the official parade route, though only the Thursday date – coinciding with Trump's nomination acceptance -- appears to be promoted.

In a bid to discourage potential problems among Trump supporters and opponents, activist leaders including Bresler, a local tea party activist and a representative of Stand Together Against Trump last week hosted a press conference urging peace.

But passionate opposition to Trump will be aired in a state with open-carry laws, causing some concern as partisans announce plans to bring firearms. Water guns are banned from a 1.7 square mile zone around the convention, but real guns can legally be carried near the convention except inside venues protected by the Secret Service.

New Black Panther Party Chairman Hashim Nzinga last week told Reuters members may take advantage of Ohio gun laws. Pennsylvania delegates also have expressed interest in packing heat where it's legal, and a top organizer of Citizens for Trump has hinted arms will be visible at their rally.

“I wish Ohio wasn’t an open carry state,” Bresler says. “You don’t see people in Cleveland ever walking around the city with holstered guns, but you’re going to see that during the convention. You’re going to see it from people on the left and people on the right. And that makes me uneasy.”

In the event of mayhem and mass arrests, the National Lawyers Guild's Ohio chapter is inviting activists to dial their help lines from jail. The Reporters Committee for Freedom of the Press has set up its own hotline for journalists arrested while covering events.

City officials have scoffed at the possibility of seeing a massive number of arrestees, and have been reluctant to discuss plans, leading to concern about what exactly those plans may be – and how they would jibe with a recent ACLU lawsuit settlement agreement that requires protocols for mass arrests that allow for quick processing.

Though all indications are that it will be a tense week, what might trigger problems is unknown.

Tim Selaty, director of operations of Citizens for Trump, recently suggested to U.S. News passions could boil over as radicals of all stripes come face to face.

“You’ve got Westboro Baptist in the mix, the KKK and David Duke, you’ve got anarchist groups showing up, Black Panthers, Black Lives Matter, communist groups showing up – you’re talking about, for lack of better words, ‘The Purge’ here,” he said.

One substantive threat to peace in Cleveland is indeed the bandanna-clad cohort of left-wing activists inclined to confront law enforcement officers, partake in unauthorized marches and ignore a raft of minor rules that could result in arrest. The exact intentions of this group, its size and level of organization are unknown, and preemptive arrests at previous conventions likely disincentivize open advertisement.

And opportunities for provocations surely will abound off the main parade routes.

Kansas’ Westboro Baptist Church plans to share its anti-gay message at an event on Tuesday at the nearby Cleveland State University, and activists of all sorts have provisionally booked slots at an official soap box near the convention center.

One of the speakers on that podium will be Jose Loayza, a Utah-based attorney who founded the group "Illegals for Trump," which has a small following on Facebook.

Though Trump’s promises to deport people in the country illegally and build a border wall to keep workers without the proper documentation out has been the spark for some of the angriest activism against him, Loayza says his election could be good for that group.

Loayza, who has a Thursday afternoon speaking slot – on the same night as Trump’s acceptance speech, says he’s a legal immigrant from Peru and that he’s not sure any actual residents in the U.S. illegally will attend, though he says he represents about 20 people in active immigration cases.

“We basically think immigration reform will not happen unless the borders are secured, and we think there’s a better chance Trump will accomplish that. And with it will come reform,” he says. “We don’t think mass deportations will happen. Even if that’s the intention, we think we can persuade him that doesn’t need to happen.”

Loayza says he opposes Democratic pushes for a path to citizenship for residents in the country illegally. He says that polarizes the debate and that almost all his clients would be thrilled to simply be allowed to work, travel and avoid deportation – a fix similar to proposed executive action reforms from President Barack Obama on ice due to legal action, though Loayza says he’d like the change made legislatively.

As the week unfolds, activists looking to unwind or congregate will meet at a large Organize Ohio-rented "convergence center" a short walk across the river from the convention hall. A rented church nearby will house medics.

Most pro-Trump activism, meanwhile, is likely to occur inside convention venues, though longtime GOP operative Roger Stone floated protests targeting delegates at their hotels, should there be any last-minute maneuvers to deny him the nomination. Stone, slated to speak at the Citizens for Trump rally, didn’t respond to a request for comment.

Though the week's course is unclear, city officials are projecting confidence.
