I don't think Attorney General Ashcroft has used RICO against prolife protesters, yet. Janet Reno did, however, and too many of the lower level bureaucrats and local law enforcment agents may still be threatening and arresting with this in mind. I heard they're still arresting doctors under threat of these laws.
Have you heard of a case that I missed?
Yes I did, and on this site, I believe. I'll see if I can't find it for you.
