Here was some idiot’s view on the raid on William Jefferson’s congressional office:

…the FBI raid was overly aggressive. The same result could probably have been achieved with a properly executed court order. But there is conflicting precedent about how much legislative-branch protection the Constitution provides from a legitimate criminal investigation.

The current matter hopefully will get to the Supreme Court quickly. Some historians are saying it is the first raid of a representative’s quarters in 219 years. It could be the last. Although it’s hard to work up much sympathy for a “culture of corruption” Congress, the need to keep men in black from breaking into the offices is almost a no-brainer in any high-school civics class. (emphasis mine)

A search warrant doesn’t count anymore?

The feds must need some super special “begging warrant” to go after congressmen, where instead of doing an actual search they just send someone to kneel outside of the office & say “PLEEEEEEEASE let us investigate!!”
