Shallow thinking like this demonstrates WHY our country is going in the toilet. You just don't get it and I don't think you ever will. Here's MY take on it; if YOU don't like Colorado's way of dealing with things, YOU get out! There are certainly plenty of states where you'll be welcome with those views. No need to go round to each state to ruin it.It was a condition on the lease! If he didn't like it, he didn't have to move in. Everybody, especially you folks in Colorado, is rightfully concerned there may be a George Zimmerman in their neighborhood, or more like Eric Harris, Dylan Klebold and James Holmes lurking in the shadows.
My guess is that this guy was showing them off, making sure people knew he was armed and still a lean, mean "killing machine," and not to mess with him because he has a "constitutional right" to stand his ground (wherever he happens to be) and blow holes in people he suspects may be up to no good, which makes people nervous.
Gotta side with the property owner on this.
Why go where your views aren't wanted except to force yourself on others.
