This is a concern area for the ACLU, but you need plaintiffs to bring a complaint. Most of the local chapters of the ACLU aren't "activist chapters," despite what people say in political discourse, and only go to court to represent real people with real grievances who want to right a wrong. Most people with grievances are more likely to work with a private attorney on contingency with a hope of some monetary gain.

The ultimate client with the ACLU is always the Bill of Rights, so the kind of plaintiffs we got when I was working there usually had broader goals. Further, the boards of each chapter decide what kind of cases the ACLU will take, and those are people from your community, so the priorities of each ACLU chapter reflects the concerns of the community, which might not necessarily be the TSA. You can imagine there's a lot of people with a lot of grievances and so usually you see the ACLU will go after the issues that are of most concern to the local community and will do the most good for the most people in preserving people's rights.

There's no end to the work, and the resources are extremely limited. It's not like Uncle Sam gives us a stipend so we can keep him honest.
