Boston was a MASSIVE intelligence FAILURE, stopping the attack was actually HINDERED by the NSA's Mass Surveillance programs.

Of the 20 terrorist plots supposedly foiled between 911 and Boston :-

3 were foiled by an alert public. (The shoe bomber, the underwear bomber and the Times Square bomber.)

17 were manufactured fake plots by the FBI encouraging people to commit terror.

NONE were foiled in any shape or form by the NSA's Mass Surveillance programs.

Boston should of been stopped.
There was plenty of evidence against the elder brother to make him a substantive risk and to get a WARRANT with probable cause.

But the authorities didn't even bother to keep tabs on him after he came back from his 6 month visit to the Caucasus.
His visit included attendance at Islamic Extremist seminars where the main speakers were Islamic hate preachers.

The FBI HAD been keeping tabs on him for 2 years prior to this, BECAUSE he posed a security risk.

Boston was a MASSIVE intelligence FAILURE, stopping the attack was actually HINDERED by the NSA's programs.

The NSA is actually putting MORE American lives at risk, NOT making Americans safer.
