This photo was taken in Serbian in 2012 during the destruction of 17,000 confiscated firearms. The most striking thing about the photo, at least to me, is what terrible quality the weapons are. Among the serviceable weapons there are piles of ancient rusted revolvers and cheap Chinese air rifles. Like most gun destruction programs, they tend to collect and destroy the lowest quality weapons, while the good stuff remains on the street (or buried underground by militants).
