We have plenty terrorists in Britain shaggy while we are in the EU. There are the lunatic Islamists which incidently are more prevalent in mainland Europe than the UK although we have them here. And of course in the UK we have IRA scum who I see were at it again in Derry the last few days
We had the britsh army terrorists in Derry also.
You also have quote a number of right wing lunatics who are quite fond of killing parliamentarians.
