female customer who physically assaulted me accosted me in public. What do I do if she attacks me in public?

When I'm not at work = public

Specifically if I'm away from cameras.

If I call Popo, she'll probably do a simple reverse and say that I attacked her in public. I'm a defendant in a domestic violence trial, so I'm quite concerned popo won't believe me.

More of a backstory in my previous post if you're interested.
