But I thought the 40 cal was supposed to be a 1 shot stop 100% of the time? I guess we better buy all the LEO's in this country new firearms in 10MM or something bigger!
As has been said, handguns are not reliable man stoppers. You will always have situations where because someone is in an altered state(due to drugs) they take an extreme amount of punishment before going down. I am not sure even had the officers been using M-4 style carbines it would have made much of a difference.
The sad truth of the matter is below a 30 caliber rifle round of some sort you are not likely to get a "one shot stop" unless you get a head shot or maybe a shot directly to the heart. Follow up shots may be needed and shots to non vital areas may be ineffective.
