Get a Warrant!

I caught wind of this News 10 investigation on Facebook.  In light of legal decisions over the last few years it is difficult to believe that anyone in law enforcement could consider this type of snooping legal without a warrant.  Probably the most frightening thing about the use of such technology is the level of secrecy involved with the manufacturer requiring non disclosure agreements and law enforcement refusing to release even anonymous data on level of use.   Not being a legal scholar I picked up a few articles for readers to check out and form their own opinion.
