Know what you mean RT, but the Police and Whitehall have indeed been quoted by BBC as associated with some odd comments ... two vehicles collided? ... purely a criminal matter not a risk to national security ... weird
As for security at front, I guess all main airports have by now moved the thoroughfare of private vehicles away from the terminal buildings but in this case the 4x4 crossed the raised central reservation to ram the doors (per taxi driver Mr Crosby and his friend Mr Barnes on BBC). Will just have to raise the kerbs up to tank trap dimensions I guess.
PS Mr Crosby said he was in absolutely no doubt it was a terrorist incident and that is why he called the BBC.
