In the days since a Manhattan grand jury voted to indict former President Donald Trump, experts who monitor extremism have watched to see whether the historic news sparks a protest movement that mirrors the Jan. 6 insurrection. 

It has not.

While hundreds of supporters showed up in Florida on Monday to cheer Trump’s short drive to his private jet before today’s arraignment, public demonstrations have not descended into civil unrest. At least not yet.

A protest in Manhattan on Tuesday morning, where Trump was due to surrender to the district attorney, appeared to feature more reporters than protestors — a pattern that has played out across the country in the last couple of weeks.  

Trump pleaded not guilty in New York today to 34 felony counts in a case that centers on allegations of falsifying business records in connection with thousands of dollars in hush money.

In his courtroom remarks during the Manhattan hearing, Judge Juan Manuel Merchan had a stern warning for both sides in the case: “Please refrain from making statements that are likely to incite violence or civil unrest,” he said. 

Back in Florida on Tuesday evening, Trump gave a speech railing against the charges, but did not call for widespread protests.

So, why aren’t extremists who support Trump showing up to support their leader? Extremism experts across the country talked to USA TODAY about four possible reasons:

1. Trump hasn’t told his supporters what to do

Last month, when the former president announced (without evidence, and as it turned out, incorrectly) that he would be arrested within days, he called on his supporters to “PROTEST PROTEST PROTEST” on his Truth social account.
