At least two Army Corps of Engineers employees have been harrassing NOLA blogger Sandy Rosenthal, founder of levees.org, for suggesting the Corps built faulty levees in New Orleans. Never mind the scientific evidence, these employees have left comments on Rosenthal's page calling her and other Louisiana residents "stupid," accusing them, without any supporting evidence, of blocking the Corps' work.
While the Corps originally seemed like it would be the one and only government agency to step up and take responsibility, it has since backed away from its original admissions of fault. As you saw in this video, the Corps' response to Rosenthal's accusations - claiming just one employee is at fault (despite Rosenthal's evidence to the contrary) and refusing to take action to stop such abuse of government computers - is just more of the same, part of a long pattern of denying responsiblity and ducking accountablity. It would not be hard for the Corps to stop their employees from harassing Rosenthal; the House of Representatives bars House employees from editing Wikipedia, and I can only think of one or two violations, so such internal fed policing has been done before.
