“The majority of firearms used in criminal activity are obtained illegally,” said David Chianese, a correspondent at Law Enforcement Today, published author and former NYPD detective. “Stricter or additional gun laws do not reduce gun violence.”
A 2019 survey conducted by the Department of Justice (DOJ) found that some 43 percent of criminals had bought their firearms on the black market, 6 percent acquired them via theft, and 10 percent made a retail purchase – 0.8 percent purchased a weapon from a gun show.
