Of course, I care!
As detestable as the man may be and that he probably DID murder his wife and got away with it, nothing is solved by not having a fair trial for these charges. If he doesn't get a fair trial, what is to assure that you or I would get one if somehow we ended up charged with something (God forbid!). What goes around, comes around.
This may be God's way of evening things out if he is convicted. But he still needs a fair trial. There are too many cases of injustice out there so let's pray for a fair trial.
