It's a great way to make simple and tangible all this nebulous talk of "keys" and "backdoors." I like to include this part about how it only takes one mistake to permanently ruin it all: >The Washington Post inadvertently published a photograph of all seven of the TSA master keys in an article about TSA baggage handling. The photograph was later removed from the original article, but it still appears in some syndicated copies. In August 2015 this gained the attention of news sites. Using the photograph, security researchers and members of the public have been able to reproduce working copies of the master keys using 3D printing techniques. https://en.wikipedia.org/wiki/Transportation_Security_Administration#Checked_baggage https://en.wikipedia.org/wiki/Transportation_Security_Admini...
