(Raw Story) Law enforcement can still be required to obtain a search warrant for access to citizens’ mobile phone location data, but police need not uphold the traditional Fourth Amendment standard of “probable cause” in the process of such an investigation, a federal appeals court ruled Tuesday.

(Time) – Government agents can sneak onto your property in the middle of the night, put a GPS device on the bottom of your car and keep track of everywhere you go. This doesn’t violate your Fourth Amendment rights, because you do not have any reasonable expectation of privacy in your own driveway – and no reasonable expectation that the government isn’t tracking your movements.

Surveillance video from subway stations are getting closer scrutiny recently, as transit police increase efforts to identify and arrest armed robbers and other criminals, a published report said today.

The NYPD asked transit police to pull footage from surveillance cameras some 2000 times last year — ten times more often than five years ago, the Daily News reports.

There are now 3100 cameras installed in city subway stations recording activities, officials said.

Millions of people ride the subway each day, and crime on trains and in stations is at a historically low level with an average of fewer than six felonies a day in the 468-station system, the News reported.
