As far as I know, only the prosecution has an obligation to provide exculpatory evidence. That said, if you wait to half way through your murder trial to produce the video of the one armed man stuffing the body in your trunk, that probably sets you up for interfering with a police investigation, or aiding and abetting, etc.
