The Agitator

Don't read Radley Balko's The Agitator if you want to be calm. Every time he posts it makes me so mad that steam comes out my ears.

Not by what he says, but the events he describes. This world of ours is impossibly infuriating, and he does a magnificent job documenting some of the flaws in the system that really should make every single person livid. You should check it out, because the more people know about the stuff he writes, the better.
