I really don't understand why so many sheeple seem to think one-ways are a sign of a potential terrorist. There are thousands of reasons one might end up on a one-way. If it was a giveaway of a potential threat, wouldn't the terrorists just by roundtrip tickets instead? Or would the terrorist be too afraid of breaking the airline rules to do something so unscrupulous

Same for cash. This only gives away that a person is unbanked, which many poor people are. Any terrorist could work around this by buying a prepaid AMEX at his local grocery store with cash.
