It's terrifying. Free speech should not be infringed upon.
This is obviously happening more and more. High profile cases like journalists and activists caught up in association with Snowden, like Greenwald, Poitras and Lavabit's founder... Are probably known to most here. But I wonder if most are aware even a journalist covering the dakota pipeline protests was detained by the US government(1).
