Since you seem knowlegable, could some of these kids be part of the un accompanied minors program. I worried that these kids were moved into the country without oversight or transparency and this would be a system fro abuse.
Do a little research and you’ll find there are thousands of “throw-a-way kids” in every state and most of them were sexually abused by parents or grandparents or both. And there’s no cure and no place to put them. So they’re warehoused wherever they kind find a place to put them.
Them you have those who were physically but not sexually abused who are placed in foster homes with older kids who abuse them. It’s a serious problem of which there doesn’t seem to be a solution.
