There are folks in groups such as American Patrol who dedicate nearly every waking hour to issues like this. They are marginalized. Even when they get air time on big talk shows like Roger Hedgecock in San Diego. I would check to see what other groups have in the pipeline for lawsuits before burning too much of your own time and money. You may be retracing steps already in progress.
I am well familiar with American Patrol. I am also familiar with Terry Anderson who has a redio show on illegals on KRLA here in Los Angeles. Barbara Coe is another familiar name.
They, however, have not taken on Mecha directly. They have been at the forefront of attacking illegal immigration, much like George Putnam has done for over 20 years. They have not done what Larry Klayman did against the Klintons.
It is a good idea to check with these organizations also, but I have not seen them go after Mecha "mano a mano". I think it is time someone did.
I will check on it and let you know-
