I take my comment back and say london is better than new york . They are only behind on two american cities. That proves they are in general better than almost all american cities. Do you know how newyork fell down on knees like twin towes during olympic bid against london because they have not enough infrastructure. You must know the quality of security in london. After the london bombing how quickly the police caught up the culprits. The cctv based security is the best in the world without a shadow of a doubt.
