ATF already maintains a database of lost and stolen firearms, so that if one is traced, they can identify the rightful owner. Now it seems Interpol will be establishing a database of its own:
Modeled after INTERPOL’s Stolen and Lost Travel Document System which today contains more than 33 million entries, iARMS will feature a hit alarm to the country of report when a match is detected. Replacing INTERPOL’s existing firearms tracing system, it will redirect users to trace firearms not found in the database, thereby linking the two processes of searching a database of reported lost, stolen, smuggled and trafficked firearms with firearms tracing. It will also enable states to capture their own statistics for crime-trend analysis and to assist them in meeting reporting requirements. iARMS will be piloted to 20 countries in September.
Think you’ll ever see your firearm again if Interpol traces it? Think your gun will come out of the database, if it is returned? I think the Arms Trade Treaty is practically guaranteed to expand in scope if it’s brought into being.
