Patriot Act: Expert Advice Section Unconstitutional

Here is one of those spots that I agree (so far) that a portion of the Patriot Act is Unconstitutional. Specifically this portion is very vague.

In a ruling handed down late Friday and made available Monday, U.S. District Judge Audrey Collins said the ban on providing "expert advice or assistance" is impermissibly vague, in violation of the First and Fifth Amendments.

Since there is no discrimination between advice that is related to peaceful activities and terrorism, I don't see how this can be enforced.

I still haven't found any argument that justifies this section of the act.
