GWOT quote -- slacktivist

Tight, on point.

You would expect, if these people were even slightly capable of shame or reflection, or even slightly patriotic, that their overweening gall would be mitigated somewhat by the knowledge that they have seriously wounded the very country they are sworn to serve. But this does not seem to be the case. Their brazen, reflexive self-justification isn't hampered by any such mitigating factors.

Unmitigated gall. Still a cliche, but inescapably apt nonetheless.
