Many people assume there’s nothing we can do to keep guns away from criminals. This assumption is wrong. We can keep guns out of criminal hands and shut down trafficking networks by passing common-sense gun laws.

We need a strong federal trafficking law to crack down on illegal gun trafficking networks. State and local officials can only do so much when guns arrive from other states with weaker gun laws. Ninety percent of the guns found at crime scenes in New York City were originally bought out of state and brought to the city illegally.

Now, prosecutors who want to fight traffickers must rely on a weak law that prohibits “selling guns without a federal license,” which carries the same punishment as trafficking chicken or livestock.

A strong federal trafficking law would enable law enforcement to crack down on gun traffickers—and keep guns off our streets.
