The risk of terrorism in Europe is low. Hysteria is high:
The average number of people killed in terrorist attacks in the UK in the period 2000-2015 was – 6. There are peak years, such as we have this year, and before that in 2005, and the one before in 1998, but most years are quiet.
The average number of people killed by bees and wasps per annum – 5.
The average annual number of people murdered in the UK – 520.
The average annual number of people who die in road accidents in the UK – 1800.
If you want extra measures, how about dealing with these unnecessary deaths, instead of building up xenophobia.
