So many places will have at least one bouncer or doorman. If its a very popular nightclub, especially at a concert, you can expect to see several bouncers or security guards on sight.

Government buildings are expected to have more security that just bouncers & doormen. Actually, well trained armed security or police are always on site. Its one thing for someone to crash their way into a nightclub, but not into government buildings. Yet, somehow some people were able to gain unauthorized access to a couple of key government buildings in the US & Canada.
