A Bureau of Justice Statistics (BJS) report on "Firearms Use by Offenders" found that only 0.8% of prison inmates reported acquiring firearms used in their crimes "At a gun show," with repeat offenders less likely than first-time offenders to report acquiring firearms from a retail source, gun show or flea market. This 2001 study examined data from a 1997 Department of Justice survey of more than 18,000 federal and state prison inmates in 1,409 State prisons and 127 Federal prisons. The remaining 99.2% of inmates reported obtaining firearms from other sources, including "From a friend/family member" (36.8%), "Off the street/from a drug dealer" (20.9%), "From a fence/black market source" (9.6%), "From a pawnshop," "From a flea market," "From the victim," or "In a burglary." 9% of inmates replied "Don't Know/Other" to the question of where they acquired a firearm and 4.4% refused to answer. The Department of Justice did not attempt to verify the firearms reported in the survey or trace them to determine their chain of possession from original retail sale to the time they were transferred to the inmates surveyed (in cases where inmates were not the original retail purchaser).
