To change our laws, restrict our freedoms and make criminals out of people simply because of their ethnicity or background means the terrorists win. Every time you go through an airport and are treated like a criminal by security goons means the bad guys have won; there's no need to treat you like a criminal, they can do the same job more effectively with politeness and courtesy, unfortunately the power has gone to their heads just to appear tough on terrorism.
It would mean that the terrorists "win", if that's what we were doing. But who's doing it? No one, as far as I can see.
There's no doubt that going through airports is now a desperately tedious affair because of the security checks we have to go through.
But are you suggesting we shouldn't have them?
I would love nothing more than to see the security rigmarole removed, but I suspect that the first plane that was blown out of the sky in the aftermath would bring down armageddon on the head of whoever gave the order to slacken the security checks.
Of course the terrorist threat from the IRA was appalling, and on a greater scale than the threat on the street from Islamists.
But as far as I can remember the IRA never threatened to blow planes out of the sky.
