Amid the rise in gun violence in the city, Assemblywoman Grace Meng is joining the push to pass a bill to require bullet microstamping – With gun violence increasing along with the temperature in New York City this summer, a congressional hopeful says now is the time to give cops a new tool to use to make collars in gun crimes. Assemblywoman Grace Meng, a Queens Democrat, faulted the National Rifle Association and Republicans in the state Legislature for blocking a bill to require gun manufacturers to use bullet microstamping technology. The upgrades, which the gun lobby says would be too expensive to implement, would allow police to trace gun cartridges back to specific weapons.
