A Florida sheriff has threatened to kill any protester who gets violent or threatens law enforcement as massive anti-Trump administration demonstrations sweep across the United States.

Ahead of the so-called “No Kings” protests expected on Saturday, Brevard County Sheriff Wayne Ivey warned protesters not to act violently in his jurisdiction. If they do, “We will kill you graveyard dead.”

“Throw a brick, a firebomb or point a gun at one of our deputies, we will be notifying your family where to collect your remains at,” Ivey threatened on Thursday at a press conference alongside Florida Attorney General James Uthmeier. “Because we will kill you graveyard dead. We’re not going to play.”

Ivey acknowledged peaceful protests “are part of our democracy — we invite people to share their opinions.” However, “if you let it turn violent…” he added before letting out a dramatic sigh, “you do not want to do that in Brevard County … and I believe I can speak for my fellow sheriffs around the rest of the state.”

Ivey added that he doesn’t want to “hear any whining later saying, ‘we didn’t know,”” pointing to the protests that have broken out in other cities, such as New York City, Chicago, and most notably, Los Angeles.

In California’s largest city, anti-Immigration and Customs Enforcement protests have captured significant national interest. After ICE agents swept across the city last week, targeting suspected undocumented immigrants, demonstrators called for the agents to leave and sought to obstruct them, with protests at times turning violent.

The day after the widespread Los Angeles protests began, President Donald Trump deployed the National Guard to the city, an action Mayor Karen Bass and California Gov. Gavin Newsom decried. The governor sued the Trump administration, and, on Thursday, a federal judge sided with him, ruling the deployment exceeded the president’s statutory authority and was unconstitutional. However, minutes later, the 9th U.S. Circuit Court of Appeals temporarily blocked the judge’s order, allowing Trump to keep the California National Guard deployed for now.
