Agree. Plus posting a 500K bond is no small matter. Maybe she or her parents have lots of idle cash, but usually it's posted by a bondsman. And the fee for that is 10% of the bond and it's non refundable. So, unless they have the cash, they'd have to pay 50K and never see it again. That's a fair bit of money for most of us to say bye bye to. And it's not a get out of jail card. It's just temporary. If they add more charges, she's back in jail. Still out the 50K. This is why FD isn't posting bail.
I think also they posted so she could see her daughter and get things squared away for her, now that she has lost her mcmansion home to stay in. Wouldn't be surprised to hear daughter will be in Fl with the grandparents and she fights for less time and whatever strategy she is going to come up with her attorney. Makes sense to me.
