I disagree...I think that the pepper spraying incident should have been its own story, and the consequences a second (or as an addendum to the first). Delaying news stories for that long just to include the suspensions would have delayed the major news item for too long, and although I'm not certain, I think the suspensions were announced at least three or four days since the pepper spraying incident occurred.
In this case I believe the headline accurately reflects the new story of what the consequences are. If the first version of this article was actually written during the time that the pepper spraying incident occurred, then the former title would have been appropriate at the time.
Also since the title still makes reference to the pepper spraying incident it contains all the relevant information, so its not hiding any focus; but rather making reference to something which should be obvious at this point. As with any news story, as it evolves over time, the focus is continually placed on new information or updates on what is occurring.
The issue is that, as a volunteer-run project with people contributing in their spare time, we can't always cover every up-to-the-minute piece of news. So, stories generally tend to bring in one story a little on the late side, with a good deal of background.
I don't know what your thoughts on the news are, but I'd prefer a delay in reporting that led to more comprehensive coverage, more depth, and less knee-jerk nonsense that turns out to be fake.
