Probably? I'd be going for a pre-trial settlement of some kind, if possible. But if it went to trial...
Everybody deserves a fair trial, even the guilty. Everybody is entitled to go free, if the state cuts corners on due process, or is unable to make their charges stick in court. Even the guilty. The way I see it, one of the main roles of the defense attorney is to ensure that his client, guilty or innocent, gets due process. I think it's a crucial part of the rule of law, that the state not be allowed to railroad a defendant just because they happen to be guilty.
So yeah. If Smollett can pay my fees, and he's not asking me to do anything illegal or unethical, I'd probably go to trial. Not to try to paint him as innocent when he's actually guilty, mind you. But to make sure the government puts in the effort and makes their case against him by the book. I figure, Smollett's paying me to hold the government accountable, and to exploit each and every mistake they make in prosecuting the case. I think that's an ethical approach to lawyering, and an ethical paycheck to cash.
