US cities launch campaign to crack down on unsanctioned surveillance

Coalition of officials and advocacy groups wants to return authority over domestic spying to townships and cities that legally oversee police departments

Local officials in 11 cities around the US launched a campaign on Wednesday to crack down on the unsanctioned police use of surveillance equipment, especially devices that imitate cellphone towers.

The coalition of officials and advocacy groups has said it wants to return authority over domestic spying to the townships and cities across the US that legally oversee police departments.
