Why do you think Holder is preventing Zimmerman from getting his gun back?
Z should let his Kel-Tec .380 go (not that the bastards at the DOJ will give him any choice) and get a more powerful firearm or three.
As this review puts it, “The .380 is not the first choice for self-defense experts; many of whom rate its stopping power somewhere between shouting stop in a really commanding voice and hitting someone upside the head with a lamp.”

As some pundit, I forget who, pointed out, the highest and best use of Z’s Kel-tec would be to auction it off for thousands of bucks and use the dough to buy a new arsenal.
