what, pray tell, is the pharmacological implication of the sugar???

If Andrea Yates had gotten the death penalty, that would have ended the whole matter, IMO. But the pollution associated with her five murders remains in some strange ways--so, the State is automatically tempted to go after her husband.
In other words, justice has not been clearly served, so the State is still unwilling to rest. To use my earlier metaphor, the State got a distinctly unsatisfying [short-lived] taste of justice in the form of Andrea's sentence and is now experiencing a justice letdown which makes it ravenous for more justice.
(I'm not convinced that this is a good situation for our system of retributive justice. Personally, I do think Russell Yates is a fool in several ways, but if it is criminal to be a fool, I know a fair number of FReepers who should be in jail.)

BTW, have you seen any Internet discussion of Andrea Yates's theology as potentially underlying her murder of her children? I haven't. But I can't help but remember that she said she was trying to save them from the devil. And notice that she killed them by baptizing them.
Maybe her pastor should be indicted as an accomplice to the murders.
Seriously, the whole mess is weird, isn't it?
