My condolences, sir. As a professional correctional sergeant, I can tell you there are some religous inmates who will take a man killing a preacher as a serious offense. Usually the ones who joke and laugh on the outside are the first to whine and cry on the inside.
The thing that STILL gets me is the "showing remorse" thing - most criminals are actors as well, to be able to lie thier way out of things, and they can show all the "remorse" you want, unless they don't feel like it. Thugs like this care not one whit about what anyone else feels, it isn't important to them.
The Good Lord bless you, and keep you safe, amen.
