We don't need a technlogy answer for a problem that should not exist in the first place. The SB notification should just be binned. We can travel around Europe without a problem but we can't travel within our own Isles. There is sooo much wrong with that concept.
Notifying SB of lights does nothing to aid security. Terrorists have become far more sophisticated these days and recruit natives ready to die for the "cause". The IRA have laid down arms and put the job in the hands of the politicians. The last time I looked the CI and IOM were not exactly a hot bed of terrorism. The "threat" we face these days is illegal immigrant smuggling and agian I do not see any of that from our Isles!
The last time I looked the government and the police were here to protect and serve us the people or did we become a police state while I was in bed?
