This is from the “Celebrate Public Service Recognition” exhibition on the Smithsonian Mall in Washington this weekend.

If they put a sign saying “Rule of Law” on front of the howitzer, people would figure it was just one more post-9/11 decorative change.

Some people look at the howitzer and think how easily it could be turned at Congress.

Folks don’t recognize that the barrel is already pointing in their direction.

Other photos I took yesterday of the military on the Mall are at my blog here.
