So my friend needed to buy a new camera today just before going to the airport on her way to NYC (from YYZ in Toronto). She texted me after clearing customs to say that she wanted to open the packaging of her new camera but didn’t have anything sharp to use b/c she was past customs. I suggested asking if any of the duty-free stores or restaurants had anything sharp she could borrow and loe-and-behold she was lent a pair of scissors!
Anyways, I got to wondering: she was sending me a bunch of sms messages from the airport which related to, in a sense, using prohibited items in a secure area. I started joking with her about TLAs monitoring the SMS traffic by sending some texts that contained blatantly violent ideas and other random stuff like ‘allahu akbar’.
Is there any evidence that TLAs monitor the sms traffic closest to airport cellular towers? Also, theoretically, could my friend be arrested for sending private texts about violence on planes or would authorities lack probable cause (b/c perhaps SMS datamining is in a grey-area of the law?)
