IJ does great work. They definitely have a libertarian bent, and while I wouldn't necessarily want to live in a full blown taxation-is-theft society, I do feel better knowing there are groups out there providing necessary pushback like seen here. A big case they won here in my state was returning a $40k car that was confiscated by the police because the person was arrested on a $100 drug crime.

I donate to them and encourage others to do so as well. And if you were one of the people complaining in that other HN thread about the alleged changes in the ACLU, consider donating here instead, rather than just not donating to any civil rights groups.
