Now how about taking a few classes yourself since you might need it in your country?
Doubt it. We're a bit more civilised.
Regardless of being civilized, do you honestly think that there are no Islamic terrorists roaming around Great Britain? Hmm, wonder how many have left to join ISIS and then will sneak their way back into your country.
Terrorism in the UK
Who cares, they'll be dealt with if and when they crop up.
We had 30+ years of IRA "terrorism" over here; bombings, shootings, etc, etc. We carried on with our lives as normal throughout. "Terrorism" only wins when you are "terrorised", like the "Torygraph" is trying to do in your link; instill fear in it's gullable readership.
The reality is I'm more likely to die in a road accident than be killed by a terrorist so I prefer to keep a sense of proportion and not behave like chicken little every time I might hear a bang somewhere.
