So, they wanted open borders, they've got open borders and what's happened?
Cowardly people are able to travel unhindered all over Europe carrying ammunition, guns and explosives with the sole intent of murdering people who've done no-one any harm.
One of the main obstacles to the same thing happening here more often is the Channel and although there's reasonably high security, in the face of such desparate criminals, it's still not enough.
Those cowardly people would never try to face off to those equally armed, no, they, like all bullying cowards pick on people unable to fight back.
Sooooo, what do you think we should do about it?
It's life Jim, but not as WE know it.
Live long and prosper.
