Trump had criticised his death, which occurred in police custody in Minneapolis, Minnesota. But as protests broke out and some devolved into looting,for Democratic governors to get "much tougher", warning "the Federal Government will step in and do what has to be done, and that includes using the unlimited power of our Military and many arrests."

When protesters marched in Washington, DC, Trump tweeted that they would "have been greeted with the most vicious dogs, and most ominous weapons, I have ever seen" if they had breached the White House.During the DC protests, National Guard helicopters flew low over crowds to disperse them. A subsequent investigation by the US Army concluded the incident was a misuse of military medical aircraft, the Washington Post reported."What we're seeing in Los Angeles is a perfect storm," said John Acevedo, an associate dean at Emory Law School who studies free speech and protests in the US. "There are protesters, they are violent. A perfect setup situation for President Trump, where he can use his goal of using troops against protesters."

The president does have the power to federalise National Guard troops, and will do so when they are needed overseas or states request additional assistance. But under normal domestic circumstances, the request for their assistance starts at the local level. The governor then can activate the state's Guard, or ask the president for federal assistance.US presidents have not taken control of a state's National Guard against a governor's wishes since the Civil Rights era, when President Dwight Eisenhower intervened to aid school integration in Arkansas, and President Lyndon B Johnson later called on Alabama's troops to protect demonstrators.

"We have, over the decades, developed statutes and regulations and protocols that govern how we handle civil disturbances for very solid reasons," said Major General (Ret.) William Enyart, a former congressman who also led the Illinois National Guard from 2007 to 2011.

Trump chose to "ignore all that hard-earned experience," General Enyart said.It was one day after the store became the centre of immigration protests, sparked by rumours that day labourers here had been rounded up and arrested.

Many who live in the community told the BBC they had seen immigration-enforcement vehicles in the area.It caused instant fear and panic. Then came reports about raids and arrests of day labourers at Home Depot, a place where many undocumented migrants across the US go to find work.

Protests erupted in this Hispanic-majority city, turning violent as rocks and Molotov cocktails were thrown. Authorities used pepper spray, rubber bullets and smoke bombs to subdue the crowd.But the demonstrations in Paramount appear to have spawned out of misinformation.
