Olympic security issues...

I feel ashamed for the organizers, why so many mishaps? Visitors couldn't use Visa, too many vacant seats, soldiers to close the gap... But security is the biggest issue... A boy passed guards and flew from Manchester to Rome without ID, someone lost Wembley keys... It turns out that any terrorist can easily get onboard or hide somewhere and commit attack and kill people... It seems to me that all guards are in London now, while the rest of cities were abandoned to terrorists...
