Donald Trump continues to exhibit a remarkable command of the obvious.

Ten people — nine of them students — were shot to death in Santa Fe, Texas, the other day. The nation is grief-stricken yet again by a spasm of gun violence in a public school.

The president spoke to the nation and said he intends to do all he can to protect our students, to make our schools safer.

This gun violence has been going on for “too long,” he said.

Yes, sir. It has. Several of your predecessors could have said the same thing. Indeed, I’m quite sure many of them did say that very thing, that this gun violence has been going on far too long.

What did they do about it? What did Congress do about it? What did governors or state legislators do about it? Nothing! Not a damn thing!

So now it falls on the current president to do something. It falls also on Congress. Texas Gov. Greg Abbott declared his intention to hold a round table discussion in which “everything” is on the table.

I have heard the president say the same thing, that he would be willing to discuss any issue put forward.

We have to stop this madness, Mr. President. Our children need to be feel safe. Their parents need to send them to school with the full expectation that they will return home at the end of the day.

Gov. Abbott said it well. “Thoughts and prayers” no longer are enough. The time for action has arrived. Hell, it arrived at the previous mass shooting, and the one before that, and the one before that one …

Do something!
