one question answered:
Kate called the cops
the reports say this happened at midnight .. but it's clearly not night, at least not midnight, in this video:

If Kate did call, it would point to the fact she thought she was right about whatever the reason she was calling. But the fact that she left indicates the police didn't agree and felt the children were safe and Jon was doing ok. I hope Kate was just having a tantrum and there was no real danger to the kids (other than what the parents are doing to them).
I just don't understand all the craziness, bordering on recklessness....surely she has 'people' who can help her get from one place to another.
