these airport marksmen have a gantry. so they can provide accurate fire under terrorist threat without slotting the wrong guy. reminds me of what they had at alcatraz. it’s really important to use positive language in life. one thing that struck me one time was when i was at a passport desk wearing sunglasses and instead of them saying, “take off your sunglasses”, they said “can i see your eyes please”. much nicer. always try to speak in the positive. the negation can be so combative. you never know, it could save you getting slotted
