Pretty much. Get an angle of the intersection that shows where you, the cop and the ped were. Number the points on the pic and give a detailed statement on what transpired. It can't hurt and gives you two chances to beat the ticket.
I don't know if this helps, but I waited until the last minute and got an extension to file the TBWD. Mostly because I procrastinate. Once you hand in your declaration, then the court sends a notice to the cop, who then has the chance to respond. By delaying things, I've wondered if it helped make the cop forget (despite what ever notes he had) details.
If you do go this route, do yourself a favor and write down the details of what happened ASAP, so you don't forget.
