The single mother’s life ended in a hail of bullets almost a year ago after a federal security breach.

On Saturday a 19-year-old New Jersey man was arrested after he tried to drive past a barricaded entrance to the White House and refused to stop. And in an unprecedented security breach Friday evening, a 42-year-old Texas man jumped a fence and ran to the North Portico and entered the White House through an unlocked front door.

The incident Friday came less than 10 minutes after President Obama and his daughters had left for Camp David. The first lady had departed separately for the trip. The man, Omar J. Gonzalez, was apprehended after he stepped inside the foyer. Gonzalez, an Iraq War veteran who suffers from post-traumatic stress disorder, reportedly had 800 rounds of ammunition, two hatchets and a machete in his car when law-enforcement officers searched it after the incident.

The two incidents, especially Gonzalez’s story, remind me of the case of a black single mother who clearly was in desperate need of help. Last October Miriam Carey, 34, of Stamford, Conn., was killed after she rammed her car into a barricade in front of the White House and then led security forces on a chase toward the U.S. Capitol.

The big difference between Carey and the two most recent incidents is that no shots were fired and both men were taken alive. Carey, who had no weapon, was struck by five bullets in the neck and torso while still seated in a black Infiniti sedan. She died at the scene. Her family has asked whether the use of deadly force was absolutely necessary, especially while her 19-month-old daughter, Erica, was in the car.

I, too, remain curious, despite an announcement in July by the U.S. Attorney’s Office for the District of Columbia that there was insufficient evidence to pursue federal criminal civil rights or local charges against officers from the U.S. Secret Service and U.S. Capitol Police who were involved in the shooting. Why so many bullets? Was a single woman that much of a threat?

To be clear, anyone who threatens the safety of others has to be dealt with to the full extent of the law, but it’s unclear whether those steps required Carey to be gunned down like a terrorist. She was not brandishing a weapon, and her baby daughter was in the car.
