FBI, NYPD told Capitol Police about possibility of violence before riot, senior officials say The FBI visited more than a dozen extremists before the rally last week to urge them not to travel to D.C., senior law enforcement officials said. [...] The Metropolitan Police Department in Washington is responsible for crowd control in the city, and the mayor told Justice Department officials that she didn't want or need their help.

Joyce Vance, a former U.S. attorney for northern Alabama, said the FBI has tools to monitor potential violence by domestic extremists. She suggested that the issue was one of emphasis and will.

At this stage that seems to be the important thing. Though the FBI has had emphasis there for some time, see

they need to be even more seriously focused in that area.
