chewkw, you’re always full of glib criticism, what better alternative do you propose?
Alternative? Death penalty.
In such obvious case shoot then debate later. You really cannot have a person charging at the police with a gun after just murdering someone in the broad daylight, only to get more publicity for what they had just done.
Put it this way, murdering someone in the broad daylight then shouting their religious belief can easily be considered insane, so they might walk free and to murder again in future. If they play their cards right they can claim insanity to walk free. Why take the chance?
