'Dear subscriber, you are registered as a participant in a mass disturbance'
Protesters stand behind a barricade in Kiev on January 21, 2014. After a night of violence, a temporary truce appeared to be in place with the protesters no longer launching the Molotov cocktails and stones that had marked their action since the clashes erupted on the night of January 19.
The Ukrainian government may be using mobile phone location data to intimidate protesters during ongoing civil unrest. Ukrainians have taken to the streets in recent days criticizing President Viktor Yanukovych's seeming refusal to move towards further integration with the European Union. In the capital of Kiev, some protesters have been receiving menacing text messages, apparently from the government, reading "Dear subscriber, you are registered as a participant in a mass disturbance." Andrew Kramer of The New York Times is on the ground in Kiev, and tells Marketplace Tech host Ben Johnson about the story.
