Hypothetical:
Potential client comes into your office without an appointment one day when you are pretty busy. Says he just got released from jail and needs a lawyer immediately. You meet with him regardless of your schedule and discuss his case. After providing the standard "no guarantees," "can't make any real guesses as to potential outcomes without viewing disclosure," etc., you acknowledge that if what your client is telling you is accurate he may have some legitimate defenses to his charges. You quote client X and accept 1/2 X as a down payment.
Next, knowing that some prosecutors can be very reasonable if a resolution can struck quickly saving that prosecutor from some work, you make a quick call over to the office to see if it's been assigned and is someone you can work quickly with. Sure enough it is. You speak to that prosecutor, who is a very reasonable guy, and he indicates he's actually considering "non filing" (dismissing without prejudice to gather more evidence) the case. You give him your take and some additional facts and evidence. This pushes him to decide to dismiss and not re-file unless the officers get more evidence (something you think is unlikely). You call your client with the good news. Client is very happy and exclaims that it's even better because he can come down and get his money back. You look at the guy and realize that you only spent about 60 minutes on his case from him coming through the door to you telling him you got it dismissed.
Your move?
