(Mother Jones) -- At 2:13 p.m. on October 3, 2013—10 months before Michael Brown was killed in Ferguson, Missouri, nine months before Eric Garner was choked in Staten Island—a 34-year-old African American woman drove into a checkpoint in Washington, DC. Her car, a Nissan Infiniti, had Connecticut license plates; her one-year-old daughter sat in the back. Maybe the driver knew this checkpoint leads to the White House. Or maybe not. She did soon appear to realize, however, that she was somewhere that she did not belong: Secret Service officers began hollering at her—"Whoa! Whoa!"—and she turned her car around. When she attempted to drive out of the checkpoint area, an off-duty Secret Service officer placed a section of metal fencing in front of her, even as he held on to what appeared to be a cooler and a plastic bag. She pressed on the gas, knocking the officer and barricade to the ground, and zoomed down Pennsylvania Avenue.
There was less traffic than usual this afternoon; the federal government had shut down after Congress had failed to approve a budget on time. Despite the relative quiet, a sense of unease pervaded the capital: 17 days earlier, a former Navy reservist had killed 12 people at the Washington Navy Yard. Maybe the lingering memory of this mass murder helps explain what happened next. Maybe not. Either way, the driver was now "weaving through traffic and ignoring red lights," according to a later government account, with Secret Service in hot pursuit. Soon she arrived on the west side of the US Capitol, where she drove the wrong way around Garfield Circle "almost hitting another vehicle head-on."
