I have no explanation for it other than that we are being infiltrated by semi-sentient vertebrates deemed too kooky for San Francisco.
You'll recall that a few months ago a minor panic made big Iowa news when someone reported a suspicious bomb-like device in the road. It turned out to be a roadkill muffler.
The massed forces of law and order converged and discovered he was a National Guardsman on a training run. The AP says the cops "determined the rifle he was carrying was a training model and loaded."
You go ahead and figure that out. A loaded rubber duck?
Policeman Kelly Fitzpatrick said the soldier, "didn't use the amount of moxie and common sense that should be expected in the present day." If so, I personally assign the blame less to the soldier and more to the "present day."
If the terrorists' objective was to turn us into an a diapered nation with 911 tattooed on the backs of our hands and all the courage of Uncle Wiggly, they're succeeding admirably.
