You've not got "genuine flight crew" written in to your DNA and you are not being screened by a scientist. You are turning up in fancy dress with an easily forged ID and are being screened by an underpaid and probably very bored person.
When the ID goes biometric, with the data stored on a central DB, there's a case, until then it's only safe to assume people aren't who they appear to be.
