Photo of Meredith Aby, target of the FBI warrants. She was a past Social Studies / Civics teacher at Bloomington Jefferson High School.
"A raid was also conducted on the home of Meredith Aby, another local antiwar leader who was frequently the spokeswoman for the march on the GOP convention."
"Aby is apparently also quite active in promoting her political beliefs, which lean about as far left as you can get. She is a frequent contributor on Fight Back! News, the media arm of the Freedom Road Socialist Organization, and has been a speaker at numerous events organized by other overtly socialist groups, including the new incarnation of the SDS (Bill Ayers old group)."
Here are articles by Meredith Aby and Mike Kelly writing about Columbian Unions on a pro-FARC and Socialist website. So, it does look like they were very sympathetic to a terrorist group.
