I agree, Linkat. That's how it used to be and how it should be again.
However... killing sometimes happens in the name of the common good, as in war, or police situations. Obviously we'd rather they didn't happen, but if Japan bombs Pearl Harbour, the US will strike back. And if some crazy shite has 20 hostages in a bank, the SWAT team will take him out.
Otherwise, I'm in perfect agreement with you...esp about the chain gang
