FBI Changes Story on Orlando Shooting

Here's my well-received little snippet at the Daily Paul that made the Front Page about a guy who was friends with the alleged Boston Bomber Boys.

Remember the crazy story of the guy pulling a knife in the midst of several armed men while about to sign a confession to a triple homicide? Yeah, well the director of that script sent it for a rewrite:

Initially, FBI officials said Todashev, 27, became violent and lunged at an agent with a knife while he was being questioned about Tsarnaev and an unsolved 2011 triple murder in the Boston suburb of Waltham. The agent, acting on an "imminent threat," then shot Todashev, they said.
However, later in the day, some of those officials had backed off that preliminary account, and it's no longer clear what happened in the moments before the fatal shooting, The Associated Press reported.

Man, I must be getting old, because I remember when the sources to these stories actually had names. It's starting to seem like Hal the Computer just prints all this crap out for the AP or something.

In addition to that, Daniel McAdams at Lew Rockwell has a great piece full of more tidbits:

Here is an account of the final hours according to his friend Khasuen Taramov:

"Taramov said he himself was questioned by the FBI for three hours Tuesday night. Asked what he was asked, Taramov said, 'Different kind of questions like "what do you think about bombings," "do you know these guys," blah blah blah, what is my views on certain stuff.'...
"Taramov said his friend had told him he had a bad feeling about the direction the investigation was heading.
"He felt like there's going to be a setup ... bad setup against him. Because he told me, "They are making up such crazy stuff, I don't know ... why they doing it. OK, I'm answering the questions, but they are still making up some, like, connections, some crazy stuff. I don't know why they are doing it.'"

Going across the pond, we find this disturbing account:

Adebolajo's friend Abu Nusaybah told the British media that the MI5, the UK equivalent of the FBI, had been hounding Adebolajo for some time after he had returned from a trip to Kenya:

"Mr Nusaybah said when Adebolajo returned from Kenya he claimed he was 'being harassed by MI5' after agents repeatedly called at his home.
"'His wording was, 'They are bugging me; they won't leave me alone'," Mr Nusaybah said.
"He mentioned initially they wanted to ask him whether he knew certain individuals.
"'But after him saying that he didn't know these individuals and so forth, what he said is they asked him whether he would be interested in working for them.
"'He was explicit in that he refused to work for them but he did confirm that he didn't know the individuals.'" 

Weird stuff, but it seems to follow a pattern. Has there been a terrorist attack where the "perpetrators" were totally unknown to the government beforehand?
