I call BS on this one.
There should have been a round in the tube on a Glock double action. Second, when he pulled it, he should have emptied the entire magazine into the perp defending himself while doing society a big favor. Now, if this is true, the perp lives another day to do it again to an unarmed innocent, possibly killing them.
Per the article, even the police chided Wolf for not already having a round chambered. And, after chambering a round, Wolf emptied his entire mag into the guy and then loaded a spare mag into his Glock .40 cal.
There is nothing “double action” about a Glock. WTF are people talking about?
