It's actually Police Squad, a short lived tv series that would later lead to the Naked Gun movies. The network didn't get it, the show had no laugh track and the jokes were rapid fire paced so after about 6 episodes the network canceled the show. TV Guide listed that as one of the stupidest reasons to cancel a tv show.
As far as the topic goes, cover shooters make sense, the point is to use tactics. Enemies take cover and try to flank you so you have to find suitable cover and find ways to safely maneuver between cover before you have enemies on all sides of you. It makes more sense then the older shooters where you just absorb bullets and use health kits when they show up.
