The Texas Senate has approved a broad homeland security bill that expands wiretapping authorities to include cell phones.
The wiretapping approval also would include investigations involving kidnapping, human trafficking and money laundering.
The bill limits the sale of prepaid cell phones, and says companies that provide the phone service must store the names of customers and other identifying information.
The legislation also would allow law officers to use photos and videos taken by cameras at toll booths to prosecute any crime.
Senator John Carona says of Dallas his proposal will modernize the methods police can use to fight terrorism and organized crime in Texas.
But a civil liberties group says parts of the bill go too far.
Rebecca Bernhardt with the American Civil Liberties Union of Texas says those aren't homeland security-related crimes.
