For doing what?
For arguing with or, in some cases, evening question a cop! Youtube has many cases including that of a 72 white grandmother tased for arguing (ironically the suddenly "pro-police" Fox took her side!) and a student who was tased for questioning a cop and refusing to sign as ticket (as his his right). Both were right. As a free American I should have a perfect right to argue with a cop be he an ATF agent or a member of a local police department. This is a free speech issue.
