Safe harbor laws are introduced to protect those minors who are forced to prostitute themselves.
New York has probably one of the most comprehensive safe harbor laws. Massachusetts, Illinois, Florida, there are a few states that are doing this specifically with children. Washington, D.C., for example, has a court. And basically, this has been a whole series of individual judges seeing these cases coming through their courts and becoming passionate and involved on the issue and being willing to work with prosecutors, the defense bar and service providers to establish these problem-solving courts.
What's the meaning of come through here? I guessed it should mean arrived at the court. But After looking up the word through in the dictionary, I found that through means pass a place, not arrive at a place. If someone wants to express arrive at someplace using through, he might want through to someplace, right? But what's the meaning of "coming through" in the quote? Does it mean the case only pass the court instead of arriving at the court?
