It’s difficult to feel much sympathy for retired Army Lt. Gen. Michael Flynn.

He has pleaded guilty to lying under oath to the FBI about when and with whom he met with the Russian government. He faces a possible prison sentence — once he finishes cooperating with special counsel Robert Mueller’s investigation into that “Russia thing.”

I doubt he’ll serve prison time. But that’s just me. Whether he remains free or in behind bars might depend on the quality of the goods he delivers to Mueller’s team of legal eagles.

However, Flynn now is being cast in a curious role in this probe. He stands to become the star witness for the special counsel’s office in its search for answers into whether the Donald J. Trump presidential campaign colluded with the Russian government that hacked into our 2016 presidential election process.

Here’s the juxtaposition that cannot be ignored:

Flynn stood at the podium in the summer of 2016 during the Republican National Convention and led the GOP faithful into that ghastly chant “Lock her up!” — the reference being aimed at Hillary Rodham Clinton and her use of her personal e-mail service while she was serving as secretary of state during President Obama’s first term.

I use the term “ghastly” because such conduct was totally unbecoming of a man with a distinguished military career who morphed into a leading politician’s national security adviser. Flynn, though, took the low road in that preposterous display.

Will this guy be locked up? Will he get the kind of punishment he urged for a political foe?

It’s tempting to shout “Lock him up!” I won’t do it, though.

Oh, wait! Maybe I just did.
