I think every state has a similar type of safe haven law these days. This one for NY first came out the same summer as the story in the article starts. This and similar stories were making a lot of news around the time and people were really interested in trying to help. It doesn't make things perfect, there are e.g. still occasional situations where a person isn't in their own control or in a sane state, but these kinds of changes did help thousands of cases since.

I think a lot of school sex ed programs/health classes have started teaching this to kids as well. Not all of course, as with most things sex ed.
