ANNAPOLIS, Md. (AP) -- Officials from the American Civil Liberties Union of Maryland are urging lawmakers to oppose legislation that will allow police to obtain cell phone tracking information without a search warrant.
The civil liberties group will testify in front of the House Judiciary Committee Tuesday at 1 p.m.
ACLU officials say that law enforcement should obtain a search warrant based upon probable cause before accessing this information.
According to the ACLU, mobile phones register their location with cell phone networks several times a minute.
Officials say that knowing a person's location over time can invade his or her privacy.
