Cool, if you’re two miles from the airport and want to identify Aunt Nelda’s actual plane before she lands. Not so cool if you’re a terrorist with a stinger missile who wants to send Aunt Nelda to hell for posting a photo of pork-laced bullets on her Facebook page (I’m not making this up about the pork-laced bullets. A company in Idaho coats bullets in pork-infused paint for those who not only want to kill Islamic terrorists, but also prevent them from entering paradise).
