This is shocking to me on so many levels - extrajudicial execution on
tape with Americans involved. Drug smuggling is a problem and all, but
this isn't like a police car chase where there is clear danger to
bystanders. Couldn't the authorities avoid deadly force?!? From the
tape it seems like the authorities were very concerned about the
proximity of the border but even if they would have had to let the plane
get away, that is no excuse for their trigger finger to do the police work!

Does anyone have any more context on this incident? Anyone know how
common this is? There was a family of missionaries that was shot down a
few years back in a similar anti-drug operation. Makes me sick.
