"The Court Security Improvement Act of 2007"

The identity of government thugs must be kept secret:

"This perfect example of typical police state legislation says that whoever knowingly makes restricted personal information available about a "covered official", or a member of his or her immediate family, supposedly "with the intent to threaten, intimidate, or incite the commission of a crime of violence" against him, her, or it will be fined, imprisoned for no more than 5 years, or both.

What it boils down to is that publishing names, addresses, phone numbers, or other information attached to (just to name a handful of examples) the federal thugs who murdered the Branch Davidians and destroyed their church, members of Randy Weaver’s family, or (had this law been in place then) the troops who assaulted the Warsaw Ghetto and the guards at the Nazi concentration camps, is now forbidden. In short, it has been made a felony to identify one’s criminal oppressors."
