Why am I surprised?! (The rich get richer.) BTW, what was your old firm's response?
The partner asked me if I wanted the "honor" of representing the King family. I wasn't crazy about the idea, and was even less so when I went to their website and found that it contained ideas that I felt were communistic and decidedly leftist. I reported my findings to the senior partner, declined to participate, and left it at that.
I think that they really wanted to be able to say that the firm represents the King family, and were annoyed with me that I didn't want to waste my time on them. As it turns out, no one else in the firm wanted to waste precious billables representing them, either.
They can pay for a lawyer, just like everybody else...especially with all the money they make shaking down everyone who dares to use an MLK quote.
