FBI - Incompetent Or Complicit ???

Here is yet another report excusing the FBI for not stopping a terror attack on US soil:

Wednesday’s terror attack in London by a man who had been known to British law enforcement is just the latest reminder of how difficult it is to prevent an attack before it takes place. Here in the U.S., in just the past three years, more than 100 people have been arrested for ISIS-related crimes. The FBI devotes significant resources to identifying potential terrorists and sometimes spends years tracking them. The terror attack in Garland, Texas, two years ago was the first claimed by ISIS on U.S. soil. 

It’s mostly been forgotten because the two terrorists were killed by local cops before they managed to murder anyone. In looking into what happened in Garland, we were surprised to discover just how close the FBI was to one of the terrorists. Not only had the FBI been monitoring him for years, there was an undercover agent right behind him when the first shots were fired.

As I noted in this previous blog post, it's EASY to prevent attacks before they take place. The Israelis do it all the time:

The FBI, on the other hand, arrests only patsies whom their agents ensnare in sting operations while letting REAL threats roam free until they attack someone.

How many more times does this have to happen before we say enough is enough and demand to know what the f--k the FBI is doing? Are they merely incompetent, or are they complicit in these attacks?
