One of the greatest weapons you can have as a perp is presence and … TWO of the greatest weapons you can have as a perp is presence and confidence. Remember, perception is reality. Show up to an airport in a Land Rover and tailgate in with someone, smile and wave… we all know what a pain it would be to have the auto gate close and reopen. As an example, the touchpad at the NE Ts entrance at KPWK is sticky so it’s annoying to access.
Honestly if it was me, I’d hit a bigger airport where you may get more transients and can “blend in with a crowd”. Risk of getting on camera is worth it, as that’s really only detective well after the fact… rather than preventative.
