I think my biggest concern would be my kids. They never shut up the way it is and if they were present, anyone trying to interagate them would probably be successful. So what would one do in this type of situation? Or would this make for a good thread to post?
"Honey... get the kids out of here-they don't need to see this any more than they already have!" (this can even be said with 911 on the phone, I think. Opinions on this are earnestly solicited) This takes care of your concern for their well-being as well as your concern about them babbling and getting you a cell with Bubba. Have a trusted neighbor or grandparent to whom they can be taken and then "honey" can come back to be supportive to you. She should know also to shut her mouth and say nothing to police prior to getting legal counsel lined up. If she is your wife, I think even as a witness, she can't be compelled to give testimony against you.
I am NOT a lawyer.
This is NOT legal advice.
