Philadelphia cops admit they put Google Maps sticker on surveillance vehicle

The Philadelphia Police Department has refused to answer Ars’ questions about how or why it deployed an unmarked police vehicle equipped with at least one license plate reader and a bizarre Google Maps decal.

Lt. John Stanford, a spokesman for the department, repeated a statement he previously sent to Vice Motherboard, which broke the story on Thursday.

"We have been informed that this unmarked vehicle belongs to the police department; however, the placing of any particular decal on the vehicle was not approved through any chain of command," he wrote. "Once this was brought to our attention, it was ordered that the decals be removed immediately."

Ars specifically asked if only one such vehicle was disguised as being a Google vehicle, who authorized this deployment, and whether the PPD has used similar tactics in the past. Lt. Stanford did not respond on any front.

[UPDATE 7:05pm ET: Lt. Stanford has now responded, saying yes this was the only one, and no, the PPD has not used similar tactics in the past.]

A Google spokeswoman told Ars that the vehicle is not a company car, adding, "We are currently looking into the matter."

Vice Motherboard reported earlier that it found this vehicle after from a tweet by a University of Pennsylvania computer science professor.

As Ars has reported for years, license plate readers are used by law enforcement agencies big and small nationwide as a way to automatically scan, record, and analyze potentially wanted or stolen license plates. Police have long argued that they are necessary tools to catch wanted criminal suspects, while privacy advocates have expressed concern that the data collection is too broad and often is retained for years on end. In Oakland, California, for example, the "hit rate" (wanted cars divided by all scanned cars) is just 0.16 percent.
