That show kicks ass! I watched it growing up and still watch re-runs on TVLand once in awhile. It is a great example of how bad political correctness has eaten up this country. Look at all the shows like ER and you will find the same plots that were originally done on Emergency! except they've been worked over by the propagandists.
On the whole, Emergency had better stunts and was far more honest about police work and fire-fighting. It started to get a little political near the end, gun control and drug war hype, but they didn't try to shape opinion, they just told a story and let the viewer make sense of it.
This was a time when guys like Johnny and Roy were expected to brave gunfire, steep cliffs, high towers, explosions, and so on and didn't make a big production of it. Brave men who risk their lives--perfect American archetypes.
Some of those stunts had to be pretty damn dangerous--rescuing people atop cranes, oil refineries, and other really high places. Not to mention the car accidents and fires.
Roy was a family man with kids. Johnny was more of an single, adventurous, outdoorsy guy who drove a Rover (not one of the pussy ones, a real Rover with the spare tire on the hood). I can picture Johnny going out shooting in the desert with his AR-15. All those characters were really down-to-earth types--no one star trying to steal the show, no "pretty people" except maybe Dixie. You couldn't even make a tv show like that today. You'd have to have a token black guy on the squad, you couldn't have episodes that showed incompetent paramedics.
I never saw the episode mejames describes, or at least I don't remember it. Pretty funny that the teargas caught the couch on fire, in light of recent events.
