In a fairly stunning win for mobile phone privacy, the Supreme Court has ruled that law enforcement agencies must obtain a warrant before they can demand and receive from mobile carriers and mobile providers access to the cell phone location data (known as ‘cell site location information’, or CSLI for short) of a given cellular phone. In the case of Carpenter v. United States, the Supreme Court held that tracking a cell phone is barely different than putting an ankle bracelet on an individual and monitoring their movements, and so overturned related case law that has been around for (up to) decades.

Twitter is aflame with calls for boycotts of Rupert Murdoch, his ‘News of the World’, ‘News of the World’s’ parent company, ‘News International’, and other Murdoch holdings, as the investigation of News of the World’s using a private detective, Glenn Mulcaire, to hack into the telephone voicemail of several young girls who had been murdered in the U.K. in 2002, and that of their families, moves into Parliament. The families of Milly Dowler, Holly Wells, and Jessica Chapman have all been informed by police that each of their telephone voicemail accounts may have been hacked, each within days of each girl’s disappearance, and each by Mulcaire, trying to get a scoop for News of the World. Among other things, Mulcaire is alleged to have hacked into Milly Dowler’s voicemail on her mobile phone, and deleted some messages, which caused Milly’s family to continue to hope that she might be found alive when she had already been murdered, and which interfered with the police investigation. Calls for Rebekah Brooks, head of News International, and a personal friend of British Prime Minister David Cameron, to step down are escalating, putting the Prime Minister in an awkward position, particularly as his Communications Director, Andy Coulson, also formerly of News of the World, has already been forced to resign his position with the Prime Minister.

Exploding cellphones are not an urban legend. In fact, another exploding mobile phone battery has killed another man (yes really). The incident, which happened over the weekend in China, is the second time in a bit over a year that a cell phone battery has exploded and killed someone. The last time that a cell phone battery exploded and killed someone, the force of the blast broke their ribs.
