I congratulate Kristen Crabtree on her decision to have the FBI's charges against her heard in court. The FBI has no case, and it is important that this be shown publicly, in court, and not hidden by private negotiations.
First, the FBI had every reason to believe that publicity and controversy would surround its recruiting efforts on the campus of a public university. If a single photograph in a student newspaper can compromise the effectiveness of an FBI agent (as the agency claims), the FBI should send less-sensitive personnel on these public recruiting missions.
Second, trying to yank a camera away from someone because you don't think they should take a picture is the behavior we expect from Sean Penn or the South African police, not an agent of the FBI. If the agent had legitimate reasons for keeping Ms. Crabtree's pictures from being published, this could have been accomplished through the courts.
The FBI agent incited the incident by trying to use physical force to take Ms. Crabtree's camera away; biting the agent's hand was an understandable act of self-defense.
