In what historians may one day record as the least strategically sound decision of the 21st century, a suspect approached a security checkpoint near the White House on Tuesday and opened fire on Secret Service agents - according to reporting by the BBC.

The result, as anyone with a passing familiarity with how elite federal protective details work might have predicted, was not great for the suspect. Officials confirmed the individual was killed after agents returned fire. Because of course they did.

What we know

According to BBC reporting, the suspect walked up to a checkpoint in the vicinity of the White House and discharged a firearm at Secret Service personnel. Agents responded, and the suspect was shot and killed at the scene.

One bystander was wounded in the incident, officials confirmed. The nature and severity of that injury had not been fully detailed at the time of reporting.

The White House was not breached, and no Secret Service agents were reported killed or seriously injured.

The checkpoint system

The perimeter around the White House is one of the most heavily secured pieces of real estate on planet Earth. Multiple layers of checkpoints, armed agents, counter-assault teams, and surveillance infrastructure ring the complex. Approaching one of those checkpoints with a weapon drawn is, to put it diplomatically, not a winning move.

Secret Service protocols in active shooter situations are well-rehearsed and, as Tuesday's incident demonstrated, effective - at least in terms of neutralizing the immediate threat.

Investigation ongoing

Authorities have not yet publicly confirmed a motive, the identity of the suspect, or where the bystander injury occurred relative to the checkpoint. The BBC report notes that officials were still working through those details.

Investigations into incidents involving Secret Service use of force typically involve both internal review and coordination with other federal agencies.

No sitting officials were reported to be in immediate danger during the incident.
