When my some was injured I used wet wash rags on his head. I don't believe her wetting down towels indicates anything other than she isn't trained in first aid. And I don't believe for a second she was sitting around doing nothing. The prosecution's own audio expert testified she was moving back and forth from the kitchen to the living room. She can also be heard, very clearly, telling Damon to hold on and screaming for the ambulance to get there.
The same cop who claims he told Darlie to help with the boys is the same cop you can hear, on the tape, telling her to "lay down... Ok... Just sit down." That's a bit of a contradiction telling someone to sit down but wait... Get up and help.
