FBI: LAX shooter wanted to kill TSA officers

CNN has learned the LAPD visited alleged LAX gunman Paul Ciancia's apartment the day of the shooting. They missed him - and the chance to save a life - by just 52 minutes.

We are also learning why Ciancia may have been targeting TSA officers at Los Angeles International Airport.

According to the FBI, investigators found a note that said he wanted to kill TSA officers and "instill fear into their traitorous minds." But was Ciancia part of an anti-government movement rising in popularity across the U.S.?
