Here's my logic. Guy, all tatted up with long hair, the whole nine yards, INCLUDING orange prison jumpers (so is it ten yards?), accused of stealing by a man who has a gun. Already, Kelly doesn't look like the sort anyone would trust (no offense) so, If I were Mr. Moores, I would shoot him soon as he started talking, given the situation. Also, the idea of using his body as bait, after they deal with him, if they decide to, then they should move it several thousand metres away and shoot off some rounds over there, to draw away the infected. Least, that's what I would do.
