Dismissing facts by quoting them with irony

Imagine a person who witnesses six police officers beating an unarmed teenager who doesn't show any signs of resisting arrest or fighting back. The next day he reads an article about the incident in the local newspaper, but the article is filled with outrageous errors and outright lies.

So this person blogs about the incident, criticizing the police and media both.

A couple days later, another blogger responds by stating at least some of the facts, but with an ironic twist, like this:

"Some wacko conspiracy theorist seems to think there's something going on between the police and the media. First, he says six police beat a helpless, unarmed teenager without physical provocation. Yeah, right - that sounds SO logical. Then he claims our local newspaper lied about the incident. Gee, I guess there must be some SECRET SOCIETY linking the police and the media, huh?"

If I interpret this correctly, it doesn't really sound like a fallacy, because the second blogger doesn't appear to be making an argument. He's essentially just insulting the original blogger.

But if ad hominem attacks can be considered fallacies, could this be classified under ad hominem, or something similar? Do you know if there's a name for this kind of stunt - where you mock people by imitating them, quoting them in an insulting manner or suggesting that even their most truthful statements are bizarre?

Great question. Here's what I think:

1. Yes, ad hominem, for sure.

2. Also, remember that real conspiracies occur all the time. That's why we have laws against them. The difference is between conspiracy theories for which we have evidence and conspiracy theories for which we don't have evidence. Note: questions are not evidence. They're just questions.

E.g.: we have evidence that the Watergate conspiracy was real. We don't have evidence that the moon landings were faked.

3. And, of course, people tell lies. That's not a fallacy, although it is bad.

See poisoning the well.
