Raising questions after DC shooting

Is this accurate?

(Miriam) Carey veered past a bollard, finally crashing into a barricade not far from a guard booth. She is said to have attempted to flee on foot as more shots rang out. She fell fatally wounded.

Wouldn't fleeing on foot negate the using her car as a weapon argument presented against the otherwise unarmed mentally troubled woman who was gunned down by government police or officers near the U.S. Capitol on Thursday.

And even the earlier shoots fired at her moving vehicle should raise questions. The Washington Post takes note:

The vast majority of big-city police agencies — including in the District — prohibit or strictly limit their officers from shooting at moving vehicles. But it’s unclear whether the Capitol Police or Secret Service violated their policies during the chase or the shootings.

Have we become a nation where there's one set of rules when it comes to normal policing - and a far more lethal thresholds when it comes to protecting government elites?

Shortly after Thursday's fatal shooting, the House of Representatives rose to give police and other agents a standing ovation for the way the incident was handled. At best, such a gesture was premature, and perhaps totally inappropriate. But then again, the way Congress works these day, it frequently seems to bestow approval before its members have a clue about what they're approving.
