The shootings in Aurora and Wisconsin demonstrate the total inability of DHS, FBI, ATF, CIA, TSA and other police and intelligence agencies to defend against the lone gunman.

These shooters belong to no organized militia or known domestic terrorist group.  They operate totally under the radar and are very effective in carrying out their diabolical plans.  Whether or not these incidents are false flag operations remains to be seen.  Whether or not these individuals are targeted individuals driven mad by their torment is also a viable question.

Whatever the case, the lone American gunman scenario keeps the Feds awake at night, because, even with their huge intelligence operations and the continued usurpations of Americans' civil rights in the name of security, there is no security.  One guy proficient with a handgun can kill a roomful of people in three or four minutes or less just about anytime he wishes.  You are on your own out there.  There is no defense, unless some armed citizen is able to take him out.  So far, this has only happened once, when a church security guard took out a shooter.  So those who will surrender liberty for the myth of government security deserve neither.  And they will get neither.

Each incident such as the two shooting incidents mentioned here proves it.
