From the post: > The second justification is to search for something called “sheet explosives,” which are apparently thin, flat explosives that can be hidden within sheafs of paper or photographs. In a case decided by the 9th Circuit in 2011, a man was arrested after TSA screeners found child pornography in his checked baggage, and while a district court ruled that the agency’s search of a stack of the man’s photographs was invalid, the 9th Circuit reversed, in the process accepting as justification the need to check for sheet explosives.
