Gun-Show Customers’ License Plates Come Under Scrutiny Federal agents enlisted local police to scan cars’ plates at shows’ parking lots

Federal agents have persuaded police officers to scan license plates to gather information about gun-show customers, government emails show, raising questions about how officials monitor constitutionally protected activity.

Emails reviewed by The Wall Street Journal show agents with the Immigration and Customs Enforcement agency crafted a plan in 2010 to use license-plate readers—devices that record the plate numbers of all passing cars—at gun shows in Southern California, including one in Del Mar, not far from the Mexican border.

Agents then compared that information to cars that crossed the border, hoping to find gun smugglers, according to the documents and interviews with law-enforcement officials with knowledge of the operation.

The investigative tactic concerns privacy and guns-rights advocates, who call it an invasion of privacy. The law-enforcement officials say it is an important and legal tool for pursuing dangerous, hard-to-track illegal activity.

There is no indication the gun-show surveillance led to any arrests or investigative leads, but the officials didn’t rule out that such surveillance may have happened elsewhere. The agency has no written policy on its use of license-plate readers and could engage in similar surveillance in the future, they said.
