The ACLU speaks up for the rights of murderers and rapists that we don't like, because we don't want the system to be able to abrogate the rights of politically inconvenient people that the powers that be don't like. Like Edward Snowden or Chelsea Manning. The ACLU and the EFF aren't about optics, but the underlying rule of law. We are better than a mob with pitchforks, even when we really don't like the perpetrator.
