This report, from NBC News on Friday, is very, very strange:

After a knock and announce, the front door was opened by Mr. Pelosi. The 82-year-old did not immediately declare an emergency, or try to leave his home, but instead began walking several feet back into the foyer, toward the assailant, and away from police

The report isn't just weird because of its bizarre subject matter. It's weird because it very pointedly contradicts what law enforcement has claimed happened when police arrived at the scene of the attack.

Here's the account filed in San Francisco County Superior Court by District Attorney Brooke Jenkins:

[M]r. Pelosi opened the door with his left hand. As the door opened, the two men stood in the dimly lit foyer facing the officers. Mr. Pelosi nervously but calmly greeted them. When the officer asked what was going on, Defendant smiled and said, "everything's good" and pulled his hands toward his body. When an officer turned on his flashlight, Defendant could be seen holding the bottom handle of the hammer with one hand and Mr. Pelosi's right arm with the other.

And here is the account of FBI Special Agent Stephanie Minor filed in an affidavit in the Northern California U.S. District Court:

At 2:31 a.m., San Francisco Police Department ("SFPD") Officer Colby Wilmes responded to the Pelosi residence, California and knocked on the front door. When the door was opened, Pelosi and DEPAPE were both holding a hammer with one hand and DEPAPE had his other hand holding onto Pelosi's forearm. Pelosi greeted the officers. The officers asked them what was going on. DEPAPE responded that everything was good. Officers then asked Pelosi and DEPAPE to drop the hammer.

As you can likely observe, the two accounts from law enforcement are essentially incompatible with the scoop from NBC's sources.

According to NBC's informants, after opening the door Pelosi began "walking several feet back" toward his alleged assailant just prior to the violent attack.

In both affidavits, however, law enforcement indicate that at the moment the police opened the door, the two men were standing by each other, with Pelosi's alleged assailant "holding onto Pelosi's forearm."

You can't really reconcile these two claims with each other. Either Pelosi's assailant was standing "several feet" away from him, or he was standing directly next to him "holding onto his forearm."

So which is it?

UPDATE: NBC has deleted the video from its website after claiming that it did not meet the network's "reporting standards."
