IT ONLY TAKES ONE

How many Islamic terrorists do you think there are in the UK - 5000, 2500, 1000, 500, 250, 125? At least fifty people were shot dead today by a lone terrorist in Orlando Florida.  The US is a large country with fifty states between which people can move freely.  With large Muslim populations in many states, what chance does what US have of putting a stop to this killing?  This is enough evidence for saying all countries of the EU would be safer if they were OUT.  Each country should protect its own borders.
