The Cato Institute has a site up with an interactive map of botched paramilitary police raids in the U.S. The map is released in conjunction with the Cato policy paper “Overkill: The Rise of Paramilitary Police Raids,” by Radley Balko.
UPDATE by Scott: Also read Radley Balko’s blog, The Agitator, and particularly the Cory Maye travesty.
