“Take pictures of the filth, then call your state’s equivalent of Social/Family Services................”
I think dealing with things in-family is much preferable unless you have clear evidence of abuse or deprivation which can be objectively shown. Otherwise, once you start down that path you can’t go back and involvement of the state might lead to ramifications you haven’t anticipated.
Calling social on the family will do far more harm than good to these children.
At “best” they’d go into foster care. Far from needing that though.
Keep your name in social media. Look for theirs. “Friend” them on Instagram, Snapchat, Facebook. Even use a private investigator to stay abreast of them. Make yourself available. And wait.
No lawsuit for emotional distress is going to get them back to you. You are not in a position of power.
“... once you start down that path you can’t go back and involvement of the state might lead to ramifications you haven’t anticipated.”
EXCELSIOR ADVICE!
Phoning a State Agency is like you playing the role of Wile E. Coyote leveraging a 20-ton boulder off the edge of a cliff. I don’t recall a single episode where that ended well for Wile E. Real Life is very similar. Sadly.
UNDERSTAND:
What we have in these United States is A LEGAL SYSTEM.
As such, the achievement of actual Justice is INCIDENTAL; NOT INTENTIONAL to the inner workings of the system.
You want Justice, be found earnestly in Christ the day Revelation 19:11 works out in shoe leather, ‘cuz you’ll have better luck peeling the stripes off a watermelon than getting it through the Courts.
