Martial law is meant to restore order. You don't have like the military or thank veterans for their service...but you don't have to trash people who serve their country, either. (Which, to be fair, you didn't...)
Here's an example of an article that leads to this kind of outrage porn:
We don't have the text messages, so we also don't know for certain that this rep wanted soldiers to keep Trump in power. When Trump used federal agents to enforce consequences for the people in progressive states who treated it like the wild west, that wasn't why he was doing it. He was doing it because they were committing crimes with impunity. Many of them receive trials, were acquitted and/or were released without charges (you can hold someone for 72 hours without a writ of habeas corpus, or reason for holding them...and, as an aside, Abraham Lincoln suspended this right during his administration when the Civil War was raging, so he's more dictator-like that the person you seem to despise more than everyone else in this country)
Lastly, when was the last time someone in an opposition party apologized and was granted forgiveness? Can you think of a simple example? Here are are a couple on the Dem side: Elliot Spitzer, former Attorney General and shoe-in for governor, if he didn't have the habit of cheating on his wife with prostitutes. In the same state, Mario Cuomo. His office is now occupied by Kathy Hochol, and his Presidential ambitions are worthless.
Tldr; you get nowhere apologizing, and it is used as an admission of guilt. Trump figured this out a long time ago. Hence, he never does it.
