The correct answer to this open question is the following.
Unfortunately, you did not include the article so we can read it. You neither attach the link of the article, the name of it, or the author. Without that information, we do not know what you are talking about.
However, trying to help you, we can comment on the following.
Some authors considered Nat Turner as a dangerous man. Some others, as a criminal. Most of them, as a trouble maker.
Ono of those particular articles was published before Turner had been sentenced. So this article tried to influence public opinion, portraying Turner as a criminal, causing so much fury in the community. As was expected, white people demanded harsh punishment for him.
But now we know that the article had a particular agenda. Nat Turner was not an assassin. He was just fighting for his convictions. Turner had led the rebellion of Virginia slaves in August 1831.
