I guess context must be it, because as I read through the tweet:
Planes roared over D.C.: check
Tanks rolled along the national mall: check
Brass bands resounded: check
Thousands of soldiers marched past cheering crowds: check and check
Largest show of military might in the capital in more than three decades: check
Seems as though the story hit all the points truthfully, so I didn't see the problem, especially since a substantial part of the story itself was devoted to the protests, starting with paragraph #2.
If the problem is that they reported on it with taking a clear and firm position against it, or that they reported on it at all, then that's a discussion of a different stripe. Speaking only for myself, I don't hold mainstream media to that standard.
