Was he a combatant?
US assumed he was and that was a reasonable assumption.
He had been a combatant, had paraded himself as a combatant, and no change of role had been announced.
The incursion was legal.
The killing was legal (unless he actually surrendered in time.)
Not one innocent bystander was hurt.
Not one of the children was hurt.
Pakistan did not object.
No government except Hamas has raised any objection.
UN has raised no objection.
No demos in any country except Pakistan, and very low key there.

So what exactly are Jim and Richard objecting to?
The nationality of the SEALS?
The end of an enemy of the West?
