Privacy advocates, including the ACLU, are supporting the bill.

“A lot of Americans don’t understand that their own police departments are monitoring their location by cellphone on a routine basis,” Crump said. “The law hasn’t kept pace with technology and we need more courts to conclude that a warrant based on probable cause is the necessary legal standard.”
