How many lawyers DO they have ready to go then??
Probably no more than a thousand across the country. About 15 of which are worthy of attention.
The good lawyers aren't going to waste their time showing up somewhere to watch. They are also going to demand they get paid, and there isn't that much money to pay them what they will charge.
Don't think that there are thousands of pro-bono attorneys in force. There may be a bunch (many or most of whom are law school grads perhaps with a bar card, but no real legal skills), but none of them are worth a damn. I've seen the so-called attorneys that show up for RAT causes.
