The Jewelers’ Security Alliance (JSA) reported that the total number of crimes committed against U.S. jewelry firms reported to the JSA decreased by 14.7% to 1,177 in 2015 from 1,381 in 2014. The total dollar losses from crimes committed against U.S. jewelry firms decreased from $77.8 million in 2014 to $69.3 million in 2015, a decrease of 10.9%. The JSA said that "due to excellent work by the FBI and local law enforcement agencies" there were arrests of two major smash and grab robbery gangs in the first half of 2015. As a result of these arrests, there were half as many smash and grab robberies in the second half of 2015 (24) as in the first half of 2015 (48). For the full year 2015, smash and grab robberies numbered 72 compared to 110 in 2014.
In addition, a major rooftop burglary gang was arrested, as a result of which the number of burglaries in which the criminals entered from a roof decreased from 36 in 2014 to 19 in 2015, a decline of 47.2%. The number of jewelers killed in crimes against jewelry firms was two in 2015 compared to three in 2014, and the number of jewelers who were the victims of non-fatal shots declined from 15 in 2014 to 3 in 2015, an 80% decrease. The JSA added that the long-term decline in dollar losses from crimes against jewelry firms in the U.S. has fallen by 63.2% since 1998 in 2015 inflation adjusted dollars, and a 22.5% decline in the last five years.
