I agree with OgenRwot in it being a bad shoot. While we have a semblance of the "castle doctrine" here in Colorado, it deals solely with the interior of the residence and being in fear of your life or the lives of your family. On the porch, on the grass, on the street in front of the house doesn't cut it. Preempting a supposed attack doesn't cut it, the supposed 'Bernie Goetz' defense.
