I think the main point is that is potentially proves she lied once again to the cops. The only reason they would have sent someone by to check would be if she tried to use the kids as an excuse to "get out" of the situation she found herself in.
"Please officer, give me a break, my kids are home with a sitter, I was supposed to be back by 1:30, I need to get home, please let me go, please".... yada yada...
When that didn't work it was "Oh...by the way, I was raped"...
ta da.... success...
Yes, that occurred to me, but it doesn't necessarily support the claim that she wasn't raped, just that she wanted to get out of a trip to the drunk tank, even though she probably came up with the rape claim to get out of being committed, which was something I suggested way, way back when this case first broke. It might show she was trying to come up with something to prevent being taken into custody, but once she was in custody, it would no longer have a direct influence in claiming that she was raped.
That sounds reasonable.
The police called her bluff and said they would send an officer over.
Then she was stuck.
