Indeed - dog packs are a very good reason for high-cap magazines.
A good point. Three years ago, a madman living 50 yds from my house attacked an older couple and their son, daughter-in-law, and granddaughter on Easter -- long-running feud that the crazy bastard had perpetrated. Armed with a shotgun and handgun, he killed the couple. Husband had retrieved a .38 handgun, but no match for the shotgun. Other family members barely escaped. When two sheriff deputies arrived and the nut raised his shotgun at them, they both pumped a total of 20+ rounds into him in about 3 seconds...unloaded their magazines entirely and dropped the mental case.
Now, if that's good enough for law enforcement for one wild animal, it's good enough for any law-abiding citizen against multiple animals, two-legged or four-legged varieties!
Addendum: The nutbag was arrested and charged for attacking the wife and son some years earlier with a knife. The D.A. dropped the charges, calling the incident "mutual combat." At the time, the husband's brother told the D.A. that he had signed his brother's death warrant. Boy was that true. It's not the firearm, it's the criminal or the insane person wielding it that *must* be removed for an ordered, civil society to exist.
