I'd say better pay and training is in order for a more professional jail guard to work there. However I don't think the average person would need training to know that was a dumb thing today. Now if they paid them more maybe they could afford this type of entertainment in their off hours instead.
I think it's a cover up. Those are not the clothes from the woman ... that was the guards uniforms. They had a party with the inmates and well one thing led to another.
