i believe its thou shalt not murder....for God ordered israel to kill enemies...David slayed goliath and isnt it said...he was after Gods own heart?

Murder and killing are TWO different things. Murder...has an evil intent behind it. Killing can have a justified reason behind the killing....defense of life.

Police officers and military personal kill people for the sake of perserving human life, and that isnt sin and it is justified. If it were not so then it would be sin. and God says to obey the government (unles it goes against doing the will of God). So killing people is ok as long as it is justified.
