Trump was warned about the possibility of violence from extremist right hate groups way back in May.
From the Hill:
The FBI and the Department of Homeland Security (DHS) in May warned of the threat posed by white supremacist groups in the United States.
In a joint intelligence bulletin issued May 10 and obtained by Foreign Policy, the DHS and the bureau said white supremacist groups had carried out more violent attacks than any other domestic extremist group over the past 16 years — and were likely to commit more.
The white supremacist movement “likely will continue to pose a threat of lethal violence over the next year,” the bulletin said.
The bulletin, titled “White Supremacist Extremism Poses Persistent Threat of Lethal Violence,” describes multiple grisly attacks in 2016, including an 18-year-old Chinese girl who was attacked with a hatchet while taking photos for a school project in Indiana. She suffered two-inch lacerations on her back from the attacker, who stated he wanted to kill her because of her race.
In February of last year, three “members of a local racist skinhead group” allegedly used knives to attack a group of Hispanic men in a Los Angeles County park.
In August 2016, “a self-identified [white supremacist]” allegedly stabbed an African-American man in Olympia, Wash., after seeing him kiss a white woman outside of a restaurant. The suspect told police that he was part of a white supremacist group and had come to fight “Black Lives Matters people,” according to the report.
Now how could it be that Trump had this information and nothing was done about it? Well… remember when he compared the FBI to the NAZIs because he was angry about leaks? Remember how he said over and over that the intelligence community couldn’t be trusted and that he had his OWN intelligence resources? That’s how.
