I read it myself, and I agree completely...except for your surprise at its use here. The death squad will do whatever it can to justify and/or cover for this killing.
At significant cost to personal credibility. I guess that's why it's surprising. Maybe I shouldn't be, FreeRepublic is a sort of MSM mini-cosmos; some people will look up the raw material and discover the poster is not reliably credible (or is a fraud!), but most readers won't, and some readers will be persauded by the propoganda.
