Sound a little fishy to me.
What could be the porpoise of arming these creatures?
Before we starting carping on the ineptitude of our navy, I think we should more carefully exsalmon the situation – they may not be solely at fault. Perhaps Katrina is just a red herring here, and these killer dolphins have been floundering around for months. Maybe some deranged fool let them loose just for the halibut. Whoever is responsible should have their head on a pike.
… and witness the punnery that results.
