Say Uncle has a post up that might seem familiar to you. Local cops put on a "demonstration" for the press involving firearms. They start off with shooting handguns at a bullet resistant vest & finish by shooting rifles at said vest. Vest is penetrated by rifle fire & used as a justification for the cries to get that miliary level firepower off the streets. In other words the typical bait & switch to push an "assault weapons" ban.
So if Say Uncle (or any other gun bloggers) seems to be repeating himself it's only because the anti's keep using the same tired, worn out tricks.
