When suing a multibillion dollar corporation, that has more money than sense, it's going to be a war of attrition. RDJ likely has millions and would probably prevail in court but this assumes that SCOTUS, who currently being fucked in the ass by corporations, will rule in his favor.
Sure RDJ can afford it. But it will be bloody. Like Endgame.
Which is so fucking weird! Imo, jury duty is the most direct way you can affect politics. Your voice is loudest and you have the most influence.
I have never been placed on a jury and the last time I got a summons was back in college.
