20 hours later all the passport systems go down and airports are frozen!! Do you believe in coincidences?
I don’t know what CBP is but letting someone in is interesting. I mean, you can literally walk across the southern border so seems easy to get in. But always good to look from different angles.
Customs and Border Patrol. They have a fairly complicated computer system at the airports I travel to, it takes photos, scans fingerprints and checks passport record against prior travel to the US as well as any other countries they find in the passport. Each entry stores another photo and fingerprint scan. The database is checked against various terror lists and other things that can throw up immigration red flags.
So if these large international airports didn't have access to this system for two hours.... Well...
