Sheriff Gregory Ahern wants to put Alameda County on the map as the first jurisdiction in California to use surveillance drones for law enforcement purposes, turning to technology previously used to hunt insurgents in Afghanistan that would allow police to peek inside buildings to detect heat sources of people or the lights of indoor pot growing operations.

 

Although Sheriff Ahern promised that the drones would only be used in “emergency” situations such as high speed chases, he told NBC News that the devices could also be used for “proactive policing,” including scanning buildings for heat sources such as people or lights that could indicate illegal marijuana growing operations.
