I know for a fact, because I had a friend that was in the US Marshall's Service that was involved in testing of handgun rounds shortly after this shootout occurred that all of the various rounds used by the FBI in this incident, including the pistol round that was adopted WOULD NOT penetrate the slanted windshield of a same model Monte Carlo used by the perps. The ONLY ROUND that DID penetrate was the .45 230 gr. hardball!
