One of the main things that started the question in my mind was reading a report done by, I believe, the FBI regarding the shootout with a person high on something (PCP?) and the resulting damage of the different rounds shot.

It wasn't the 1986 Miami incident, but something else...and I'll be damned, but I can't find it. Bottom line was that shooting a zombie, the .223 did nothing to stop him, only the larger caliber pistol rounds that shattered bone etc. brought him down.
