The forensic scientist for the Bridgeport, Conn. Police Department sharply criticized proposed assault weapon and high-capacity magazine bans and pointed out the small number of crimes committed by high-capacity weapons in public hearing testimony last week.
Marshall K. Robinson, who said his area of expertise is “firearm and tool mark identification,” testified at the Gun Violence Prevention Working Group, which was convened at the Connecticut State Capitol in response to the Sandy Hook Elementary School shooting. There he opposed statements from many of the other 1,300 speakers in attendance advocating for banning high-capacity AR-15 and AK-47 firearms.
Robinson pointed out that less than two percent of the firearms he has examined since 1996 that have been linked to violent crime in Bridgeport have been the caliber of AR-15 or AK-47 weapons.
“Since November 1996, I have examined approximately 2,370 firearms. Of that number 36 of them were either .223/5.56 mm or 7.62×39 mm,” Robinson said. “The percentage of those guns was about [1.5 percent].”
“I did further research on homicides and assaults in the years 2006 to 2012 inclusive. Of the 217 such cases, there were 912 bullets and 466 cartridge cases recovered. One assault involved .223 caliber and none involved 7.63×39 mm caliber. The largest number cartridge cases recovered in one case was 37 and that involved two guns. The investigations that involved the recovery of eleven or more cartridge cases was 22. Of the 22 cases, 21 involved 2 or more guns,” Robinson added.
