Well that's a lot more than terrorism in the UK and look at the amount of money and police we are prepared to throw at preventing that.
Sadly true. Both problems are insignificant and I don't think we should be throwing so much resources at either.
While we're at it we should ban wind turbines and rooftop solar because sometimes the maintenance chap falls to his/her death.
Actually we should just ban them because they're a stupid boondongle that does nothing beneficial for the massive cost, but that's a different subject.
