It has been exactly two months since Miriam Carey, a young, single, unarmed black mother and dental hygienist from Connecticut, was gunned down in the streets of Washington, D.C., after driving her black Infiniti into a security post near a White House entrance and leading police on a chase to the U.S. Capitol.

Shots were fired at Carey near the White House barrier at 15th Street and Pennsylvania Avenue, according to police. And she was killed in a hail of police gunfire after she apparently brought her car to a halt on the 100 block of Maryland Avenue NE — posing no apparent danger to anyone. Witnesses said police also fired shots at Carey on Constitution Avenue near the Senate Hart Office Building.

Yet, we still don't know how many shots were fired at Carey on Oct. 3. We don't know how many shots hit her. And all videos of the final incident have mysteriously disappeared from the Internet.

The Secret Service, Capitol Police and Washington Metro Police were all involved in the incident, throughout which Carey's 14-month-old baby was in her car. And press reports suggest the mother was suffering from postpartum depression.

For an incident two months ago that paralyzed Washington for hours, we know little about what actually happened and why a young, single, unarmed black mother was killed by police. Independent news website WND has filed a Freedom of Information Act request for the forensics report to no avail.

An attorney hired by Carey's family, Eric Sanders, asked Attorney General Eric Holder to investigate the incident. Immediately after he did, Sanders was arrested at his Long Island home for allegedly failing to pay off court settlements in an unrelated case dating back to 2005.

What the heck is going on here?

As far as I can tell, Carey did little more than make a wrong turn and bump a security barrier near the White House. She may have been disoriented, a symptom of postpartum depression, when she had guns pointed at her by law enforcement officials. But imagine the fright of a young mother at cops firing guns at her car when her 14-month-old baby is in the back seat.

What possible justification could there be for killing Carey? Why couldn't she be subdued, arrested and tried for whatever laws she may have violated? Why did armed officers of at least three law enforcement agencies allegedly execute her in cold blood? Why has there been no satisfactory public explanation of what transpired that day? And where is the public outcry over this seemingly senseless murder?

Let's talk about the video.

We live in a surveillance society. Nowhere are cameras more prevalent than in Washington, D.C. There is video of Carey's approach to the White House gate. There is video of the chase that led to her death. But where is the video of the final scene when Carey emerges from her vehicle and is shot down?

Does anyone else think it is strange - and a little mysterious - that no video is publicly available, despite the heavy presence of media on the ground, police helicopters, surveillance cameras, etc.? Does anyone believe video of those final moments just doesn't exist?

And what about the forensics report? Why two months after the incident, has it still not been released? Is anyone besides WND demanding it?

Why so little curiosity about what, from my perspective, seems to be an outrageous misuse of police firepower? Carey's family and friends have suggested she had delusions about Obama stalking her. The tragic irony is that she ultimately fell victim to a police-state mentality Obama helped foster in the capital city.

It's time for the Secret Service, Capitol Police and Washington Metro Police to come clean on the death of Carey. It's time for the public to demand it. It's time for Obama and Holder to order it.
