What is the end game here? If they know you’re part of a terrorist organization, how can you be traveling at all? If you are a known terrorist by the US Govt, then I would like to think you are in custody, not planning an overseas trip. Same goes for their affiliates. Replace the word terrorists with “serial killers” and affiliates with “accomplices”. Should we revoke passports for serial killers and their accomplices? The answer is yes, but the question is why would we not have known serial killers and their accomplices in jail?
