In This Horror Film, Blood Is All Too Real [New York Times] ‘Terror at the Mall’ on HBO
documents an Attack in Kenya.
One year ago, gunmen from the Shabab militant group in Somalia laid siege to the Westgate shopping mall in Nairobi, Kenya. Armed with AK-47s and grenades, they stalked their victims from a gourmet burger restaurant at the entrance to the vegetable aisle of a grocery store at the back.
The British filmmaker Dan Reed assembled thousands of hours of footage gleaned from more than 100 security cameras inside the mall, video from television crews and modest cellphones, as well as still photographs. Then he and his team tracked down more than 200 people and interviewed 82 of them on camera, many survivors or their rescuers. [more inside]

Verizon draws fire for monitoring app usage, browsing habits:
Verizon Wireless has begun selling information about its customers' geographical locations, app usage, and Web browsing activities. The company this month began offering reports to marketers showing what Verizon subscribers are doing on their phones and other mobile devices, including what iOS and Android apps are in use in which locations. Verizon says it may link the data to third-party databases with information about customers' gender, age, and even details such as "sports enthusiast, frequent diner or pet owner." [more inside]

Met Police to extract suspects' mobile phone data
[BBC] The Metropolitan Police, covering Greater London, are set to expand their search powers by making it standard practice to swipe contact details, call logs, and texts off of the mobile phones of anyone in custody - and retain
that data - regardless of whether the suspect ends up charged with a crime or not. Clearly not everyone is over the moon about this, seeing it as the latest sign of the steady erosion of communications privacy in the UK
and a potential breach of human rights law.

Flash Mobs Take Violent Turn in Philadelphia
[H]undreds of teenagers have been converging downtown for a ritual that is part bullying, part running of the bulls: sprinting down the block, the teenagers sometimes pause to brawl with one another, assault pedestrians or vandalize property. . . .
The flash mobs have raised questions about race and class.
Most of the teenagers who have taken part in them are black and from poor neighborhoods. Most of the areas hit have been predominantly white business districts.
In the flash mob on Saturday, groups of teenagers were chanting “black boys” and “burn the city,” bystanders said.
