domestic violence in WI

WI

Am I required by law to report domestic violence that I actually saw, in WI, and is there any way I can get in trouble for doing nothing?

The DV is at a neighbor's house. It's a long unfortunate story.

There's no law that says you have to report, so no trouble for not.

Though why would you not report it.
Somebody needs help it seems to me!

Do so anonymously perhaps, if you must.
