It ain't the gun...

Police departments around the country are finding that the .40 calibers aren't as effective if an unfortunate incident occurs and they're forced to have to use their weapons," Rutherford said. "[The larger caliber] is safer for the deputies and for the public if the unthinkable happens and we have to do what no one wants to have to do.

I'd argue it's not the .40 caliber that's not effective, but the shooters. My experience is with North Carolina Law Enforcement Officers. North Carolina requires that an officer qualify with whatever firearm that officer carries on duty. With a duty handgun that's thirty to a fifty rounds each for a day and night qualification once a year. The minimum score to qualify is 70%. There may be tactical firearms training included in the mandated yearly in-service but that's not guaranteed. I suspect this is probably the case in other states as well. Sheriff Ruthterford, I suggest the money you're going to spend on new gats for your officers might be better spent on training.
