Looks like the have tracked the perps down. I was just watching the news. Police seem to be outside the residents of one of the suspects.
As for death penalty: I am pretty much against it. Not because I have anything against scum bags dying, but because I am against innocent people dying. So unless there is irrefutable proof (I.E. footage) or the perp chooses to die (I think this should be allowed). It costs lots of money to keep people alive and fed and housed for 10, 20, 30 years, but it costs much more from the human soul to kill an innocent person. Also an exception must be made for severely mentally ill people. You could say anyone who kills is crazy (maybe), but think about every military personel who has killed people, maybe even innocents, I don't know that they were all crazy, they just believed what they were doing is right.
I also am not opposed to violence, so don't count me a hypocrite (though like everyone else, I am). I think controlled violence is one of the greatest things for society. Things like horror movies, martial arts (MMA, boxing too), even mosh pits at concerts, and violent video games are excellent ways for people to relieve their stress and experience a certain amount of violence that is innately hungered for in the human mind.
