Not in the least, my friend. No matter how much these inferiority complex-ridden terrorists attack our hot spots, life in Bombay city (or anywhere else in this country) goes on uninhibited, full throttle ahead with even more gusto than before. 
Not everybody needs security though some people get it to dramatise their existence. For the most part, there is an overall feeling of safety and security here. The security staff in the pics are bouncers/ parking attendants at one of Delhi's fun nightclubs.
Shoeb, hit me up when you're in Bombay next.
