Looks to be Australian, just going by the accents and that they drive on the left side of the road.
If something like that aired on American television there would likely be public uproar about violence on TV, rights of the accused, ect. The best we can offer are lame-ass commercials featuring a redneck in a beat-up pickup where the cab is filled up with beer, and some officer getting showered with beer when the guy puts the window down, only to ask "have you been drinking?". There was one with wine in a SUV and martini in a sports car I believe.
I agree that people convicted of drunk driving should have their license revoked for at least several years, and anyone who killed with their driving have manslaughter charges put against them. Which does happen, but only in very rare, espically grisly cases. Most of the time a shithead lawyer bargains it down to a few AA classes and maybe a fine.
My father was convicted of DWI when I was about 12, and in the car with him. Nobody got hurt but the damage was severe enough that the other guy called the police, who saw instantly that he was totally shit-faced. He didn't even spend the night in jail. Got booked on an appearance ticket and released a couple hours later. The hearing resulted in the more or less "standard" DWI penalties of having to take a 4 week "dangers of DWI" class, paying something like a $1000 fine, and pinky-swearing that he won't do it again. License wasn't even suspended, though he did get a new one that has a notation on the back that he was convicted of DWI. That's in NY, I don't know about in other states but NY usually has pretty strict laws compared to other states. Of course, he continued to drive drunk for years afterward. A few times when he was really blasted and went out I did call the police on him, giving them the tag # of his car and where he was going, but they either never pursued it or never caught him. Only recently has he decided to clean his act up, seemingly of his own will.
