Subject: Interview with an inventor of the KTW bullet
The following text is from the NRAction newsletter, Volume 4, Issue 5 (May 1990); it is an interview with one one of the inventors of the KTW bullet, and is a subset of a larger article.
We decided to go to the source, to track down the inventor of the original "cop-killer" bullet, originally marketed as the "KTW" bullet. We found the "K" of "KTW," Dr. Paul Kopsch told us that the bullet was made exclusively for police and military use. And had nothing to do with protective vests.
Kopsch: "There were a couple gunfights, police versus criminal, here in Lorraine County, [Ohio]. The ordinary .38 Special service bullet would not get through the car door. And with any degree of obliquity, it bounced off the windshield. [Police] Lieutenant Turcus, Don Ward and I thought maybe we could design a bullet which would get through the car door, and get through the windshield and get the crook out of the car ...
Kopsch explained that the teflon coating, which a host of media and lawmakers alleged was the key to penetrating body armor, served one purpose. It helped bullets go through smooth surfaces, like windshields and car doors, especially at oblique angles. The former Army medical officer likened it to the teflon tip of a walking stick. It simply grabs better.
Kopsch: "Adding a teflon coating to the round added 20% penetration power on metal and glass. Critics kept complaining about teflon's ability to penetrate body armor. That was nonsense typical of do-gooders. In fact, teflon cut down on the round's ability to cut through the nylon or kevlar of body armor."
Thus, Kopsch and police officers Turcus and Ward invented the "KTW" round. It was designed to be shot by police and military through car doors and windshields at criminals, terrorists -- not, as Chief McNamara would have people believe -- through ballistic resistant vests worn by police officers.
Could the round penetrate such vests? Again, Dr. Kopsch ...
Kopsch: "It'll defeat the ordinary ballistic nylon or Kevlar vest, but as I said, the teflon gives away its purpose and detracts from it's ability to penetrate body armor. Moreover, no armored police officer has been killed by the round, and interestingly enough the man who brought this to national attention ws the Honorable Rep. Mario Biaggi, who was in the U.S. House of Representatives at the time. When he called attention to the fact that the police were wearing bullet-resistant garments, the criminals started to shoot for the head. So Biaggi may have gotten quite a few policeman killed ...
"We never sold [KTW] to the public. Sales were always limited to the police and the military. It had been available to the police and military for roughly five years before Biaggi started this ... it was a hoax on [Biaggi's] part that got him national publicity.
