Our nation has the very best intelligence gathering on the planet. The problem seems to be whether one agency is sharing information with other agencies to keep up with all the creeps and killers that want to annihilate us and many others in the world.

U.S. officials put the radical Tamerlan Tsarnaev on a terrorism watch list months after the FBI placed him on a different watch list. The Russian government also supplied information that aided U.S. authorities about an "alert" on Tamerlan.

So, since this terrorist was well known, it raises the question whether the FBI should have kept a closer watch on him, perhaps preventing the disaster.
