"Much like 007, they have a license to kill." Actually, they do have a legal sanction to kill with very broad standards. Unlike civilian groups they have "sovereign immunity". Sovereign immunity is appropriate for honest mistakes, but not for incompetence and gross illegality, as in this case. More heads should roll than just Bisard's.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats. H. L. Mencken
