I'm inclined to believe just what it says; it's a DRILL. But the timing is bad. Would be interesting to know just when this was PLANNED.
Reminds me of the drills they had just prior to Y2K. I guess they would be negligent to NOT do drills prior to possible SHTF events.
And we would be negligent to not be aware of what they plan on doing. (Four days of urban MILITARY ops, home invasion, interogations, illegal searchs - for “one” suspected arms dealer?!?)
