It's not better, it's the only thing you should do.
As a Plan B, something to fall back on if your defense attorney is flailing, you could always film the sexual encounter. It worked for the Hofstra guys:
The weird lesson for men who have group sex in bathrooms: Film it on your cell phone. A five-minute video of the sex, which one of the men gave the cops, apparently persuaded the 18-year-old to take back her original story. At another moment, such a video might have gotten the guys in trouble for making porn and for sexting. But this time, it seems to have saved them.
You probably don't want to lead with the video, though.
