I'm not an international traveller but I can confirm that the British Police have body armour and sub-machine guns at the airports. All police now wear light body armour, black stab proof vests. British police still don't carry guns but highly trained armed response units are only a radio call away at all times. The good old British bobby is a thing of the past...

It might be a surprise to our American cousins but terrorists did exist before 9/11. Over this side of the pond we have been living with the IRA for 40 years. Thankfully we no longer have any issues with them but the Islamists have taken over as killers on our streets. Most home grown which is a disturbing fact.
