More to the point of this thread perhaps:
Would a criminal records check (CRC) prevent the London murderers getting airport passes and committing acts of terrorism in or around an airport environment?
Is it correct that when a CRC is carried out on an individual, it is only for a UK criminal record?
Would I be correct in assuming that if an individual had not been resident in the UK for long, but was a UK passport holder, that a CRC can only go back as far back as the individuals length of residency in the UK?
