Wanna know whats gonna happen?
They're gonna make you plead guilty to one charge, drop the rest, slap you with a fine, and send you on your way. Taking a dump in a public park is the same as criminal mischief, so I wouldn't worry. If it involved vehicular homocide, you'd really need to ask advice on which lawyer.
In this case, call the attourney CLOSEST to the district attorney's office where hes being charged :wink: and get out the checkbook. They're not gonna take his license or impose jailtime for an offense he reported the next day and went back to the scene.
Examples like this are a money game for small towns. They want your money, then never want to see you agin! 8)
