Can anyone name a network drama television show that isn't copaganda, or about firefighters or doctors that is still on the air and has run for more the six seasons?

Edit: Kung Fu and Nancy Drew are on season 3, we do have the CW's The Flash, and if we're generous The Equalizer is on season 3, technically not about law enforcement, even though she is a former CIA agent. A Million Little Things is ending after their 5th season.
