Federal officers stockpiled semiautomatic rifles and tried to obtain a controversial 'heat ray' ahead of tear-gassing protesters for Trump's photo op, a whistleblower says

• Federal law-enforcement officers stocked up on semiautomatic rifles hours before forcefully clearing protesters from Lafayette Square in Washington, DC, according to whistleblower testimony obtained by The Washington Post.
• Officers also unsuccessfully sought to obtain a controversial "heat ray" that can cause second-degree burns, according to the testimony, which was submitted to lawmakers by a top DC National Guard officer.
• His account contradicts previous claims by the Trump administration that protesters were violent, that officers didn't use tear gas, and that they issued legally required warnings to protesters to disperse, according to The Post.
• In early June, federal officers used tear gas and rubber pellets to clear peaceful protesters from the park so President Donald Trump could take a photo at a church near the White House.

On June 1, federal law-enforcement officers used tear gas, rubber pellets, and other aggressive tactics to remove protesters from Lafayette Square in Washington, DC, so President Donald Trump could have his photo taken in front of a church near the White House.

Hours before that, officials were busy trying to stockpile semiautomatic rifles, thousands of rounds of munitions, and controversial crowd-control technology, according to sworn testimony submitted to lawmakers by Maj. Adam DeMarco of the DC National Guard, both The Washington Post and NPR reported Wednesday.

The US National Guard and the US Park Police could not immediately be reached for comment.

DeMarco, who was the most senior DC National Guardsman on the ground on June 1, testified that a stash of M4 semiautomatic carbine rifles arrived at the DC Armory earlier that day, followed by "approximately 7,000 rounds" of 5.56 mm and 7.62 mm ammunition in the days following, including from states as far as Missouri and Tennessee, according to the testimony.

Officials in Washington also unsuccessfully sought to acquire an Active Denial System, a controversial "heat ray" that has resulted in test subjects suffering second-degree burns, arguing it could give officers "the ability to reach out and engage potential adversaries at distances well beyond small-arms range and in a safe, effective, and nonlethal manner," DeMarco reportedly testified.

The New York Times reported last month that the Trump administration considered deploying ADS technology at the US-Mexico border despite long-running "doubts over its effectiveness and morality" but that then-Homeland Security Secretary Kirstjen Nielsen shut the idea down.

"That anyone in the Department of Defense referred to American citizens exercising their First Amendment rights as 'potential adversaries' and even contemplated the use of an ADS on the streets of our nation's capital is deeply disturbing and calls for further investigation," DeMarco's attorney, David Laufman, told The Post.

DeMarco's testimony also contradicted previous claims by Trump administration officials and other law-enforcement officers claiming that protesters were violent, that tear gas and rubber pellets weren't used, and that officers issued legally required orders to disperse.

US Park Police Chief Gregory Monahan testified in July that officers issued dispersal warnings via a "long-range acoustic device," according to The Post.

But DeMarco disputed that claim, testifying that no such device was "on-site at or near Lafayette Square on June 1," adding that the warnings were issued via a handheld microphone attached to a standard megaphone and that they were "barely audible" from his position 30 yards away — while the protesters were at least 50 yards away.

In late June, congressional lawmakers began investigating officers' use of force against protesters in Lafayette Square and have heard testimony from both DeMarco and Monahan as well as protesters, journalists, and other witnesses.

DeMarco's testimony comes as reports surface that US Attorney General William Barr told federal prosecutors to be aggressive with charges against violent protesters, called for consideration of sedition charges, and called for criminal charges against Seattle's mayor over the city's autonomous police-free zone during the protests earlier this summer.

The reports paint an even more detailed picture of the Trump administration's aggressive response to protests against police brutality that have emerged since George Floyd's death in Minneapolis in May.
