Why has the FBI not acted against us since 2001?

Well they are bungling fucking idiots for a start - and probably also scared of their own shadows after 2003.

Online threats target Denver investigators - Anarchist says e-mails harmless; feds disagree
By Jim Hughes - Denver Post Staff Writer
Monday, July 07, 2003 - An anarchist using the online moniker “Professor Rat” has threatened the lives of two federal terrorism investigators in Denver, advocating that they “need killing.” The threats name an FBI agent assigned to the local multiagency Joint Terrorism Task Force and the government’s lead prosecutor of terrorism cases in Colorado.
Although those who travel in the same online circles as Professor Rat say his provocations are not to be taken seriously, officials say they are concerned about the threats, which were sent to an e-mail listserv and posted on the Internet in April.
“The recipients of the threats have no way to discern their validity,” said Jeff Dorschner, spokesman for the U.S. attorney’s office. "They cause fear and they disrupt lives, and it’s for that reason that they’re taken very seriously.
“It’s more than the individual targets. It’s the families and those associated with them,” he said.
That is the purpose of the postings, an Australian man who admits to using the Professor Rat name and to posting these kinds of threats said in a telephone interview and a series of e-mails: To scare people out of working for the government.
