“Wipe that smirk off your face … “

Look at this picture.

It is Texas Attorney General Ken Paxton posing for his jail-booking mug shot.

Does that smirk bother you? It bothers me. It makes me wonder why politicians feel compelled to smirk like that when they’re being booked into a lockup, a place with sturdy iron bars meant to keep prisoners inside.

Former Texas Gov. Rick Perry smirked like that when he was booked after being indicted more than a year ago.

Paxton’s mug shot illustrates, I guess, a certain smugness that politicians have when the criminal justice system tags them with an allegation that they’ve committed a crime.

In this case, a Collin County grand jury has accused Paxton of securities fraud. It’s a big deal. The man could lose his political career if a jury convicts him of the felony accusations.

This mug shot reminds me of my dear, late mother.

I had this bad habit of smirking like that when Mom scolded me when I was a kid. I took the habit with me into the U.S. Army in 1968; our drill sergeants would get in our faces for this or that during our basic training and my reaction would be to, um, smirk. It drove these combat-tested soldiers crazy … and it damn near got me into some serious trouble.

Mom would get so angry she’d order me to “wipe that smirk off your face or I’ll wipe it off for you.”

Attorney General Paxton’s smirk will disappear if a jury hangs the “felon” label on him.
