Amber Alert a few days ago

I don't know. It rubbed me the wrong way to see an amber alert on a 17 year old with a tatoo after she willingly got into a car with her boyfriend.

Not sure what the tattoo has to do with your concern.

And getting into a car "willingly", or appearing to, doesn't determine that a person isn't acting out of fear, or under threat of harm, depending on the situation.

Other than that, she's a legal minor who was considered to be in "grave or immediate danger" for whatever reason. It doesn't seem to be the typical case but I don't know that it falls outside of what the system was intended for.

Knowing more circumstances might paint a different picture, either way.
