I have seen French Marines patrolling Disney Paris near the Eurostar terminal.
Remember we have had military exercises at Heathrow but as armed police and real military armed personnel on British streets is so rare politician s seem to shy away from the obvious.
Under UN auspices we had armed Army patrols in Limasol; army patrols in NI; what is fundamentally wrong about show of force on the mainland? Scare the bejesus out of the innocent population?
