Trying to step back, we still see the usual arguments being made.
Can't tell fantasy from reality... all dramas carry messages and only fools or liars deny it. They don't compel the audiences to act on those messages and condemning them as contributory to any acts is equally foolish. But no one has done this, except confusing a gibe with a real wish. The message carried by a drama, even it's acceptance of the status quo, is always a legitimate target of criticism.
That's not totally objective... doesn't have to be. It is convenient to pretend that all opinions are equal but they aren't. Some of the heat in the last exchange developed from posts trying to justify the murder when the drama itself couldn't. Accepting that the guy would really say something like that or that it would really be true requires a completely uncritical, nearly unconscious, viewing. Incompetents like to say taste can't be disputed, but the sorry truth is that this sort of thing isn't like saying you prefer salt to sugar, it's like saying baking soda is sweet, then pretending it's all subjective.
It's not real... this is closely related to the fantasy/reality dichotomy, but is aimed more at the idea that since it's all fictional, it doesn't matter: It has nothing to do with reality. Therefore, enjoying watching a Kennex murder a loudmouth doesn't suggest I really wish I could blow away loudmouths. The problem of course there isn't any reason to care about fiction unless we relate it to us in some fashion. Our feelings about the real world have everything to do with what we enjoy in fictional entertainment. We know perfectly well that it's not real, and sometimes we even consciously enjoy stuff precisely because we know it's not real.
Everybody actually knows this, and that's why a simple announcement that the ending was unconscionable and the show's over was instantly answered with a rude remark. Nonetheless, people will persist in watching TV and movie dramas with their feelings engaged and they will persist in relating them to the real world, never for a moment forgetting it's all fictional. This is the natural thing to do. It takes a pretty diminished capacity to leach drama of all significance. If you really don't invest anything emotional, then don't give a shit when someone criticizes it.
I didn't like Kennex shooting a suspect he already had in custody either, but your habit of negatively judging people for their preferences in fictional TV shows is really tiresome and ruins damn near every TV series thread you participate in, which is unfortunately a lot. Every time I start watching a show and see your user name turn up in the commentary thread it makes me not want to post there and have to put up with your tedious pontificating on how no one else is as deep and thoughtful as you are because you see the ugly truth behind everything.
Go rain on someone else's parade for awhile and let people enjoy their shows without being compared to war criminals because Sipowicz slapped a suspect with the Yellow Pages and they didn't immediately report it to The Hague on account of it didn't actually happen.
Meanwhile, you wore an avatar for years representing a country which participated in the largest mass murders in history, so what conclusions should we draw about what you support from actual real life events rather than a silly TV show about robots in the future? Not to mention your implication that people who supported Kennex's fictional actions against a fictional villain should meet up with a real life version of him who would kill them, which you quickly copped out on and tried to turn back around against the person who called you on it even though it was perfectly obvious to everyone what you were saying.
