I often tell my students that where they see a problem, they should find the opportunity. Well, we’ve been told over and over this weekend that we had a big problem with misinformation after the Boston Marathon bombing. Breaking news, haven’t you heard, is broken.

So I see an opportunity, a big journalistic opportunity. I also tell my students this:

* Journalism should add value to a flow of information that can now occur without media’s mediation — verifying facts, vetting witnesses, debunking rumors, adding context, adding explanation, and most of all asking and answering the questions that aren’t in the flow, that aren’t being asked, i.e., reporting. Let’s acknowledge reality: There’s no stopping or fixing that flow. What witnesses see will be shared for all to see, which is good, along with rumors, rank speculation, and the work of the New York Fucking Post, which is bad.

* The key skill of journalism today is saying what we *don’t* know, issuing caveats and also inviting the public to tell us what they know. Note I didn’t say I want the public to tell us what they *think* or *guess.* I said *know*.

So the opportunity: If I ran a news organization, I would start a regular feature called, Here’s what you should know about what you’re hearing elsewhere.

Last week, that would have included nuggets such as these:

* You may have heard on CNN that an arrest was made. But you should know that no official confirmation has been made so you should doubt that, even if the report is repeated by the likes of the Associated Press.

* You may have heard reports repeated from police scanners about, for example, the remaining suspect vowing not to be taken alive. But you should know that police scanners are just people with microphones; they do not constitute official or confirmed police reports. Indeed, it may be important for those using police radio to repeat rumor or speculation — even from fake Twitter accounts created an hour ago — for they are the ones who need to verify whether these reports are true. Better safe than sorry is their motto.

* You may see on Reddit that people are speculating about who perpetrated these crimes, including speculation that it *could* be a missing college student. But you should know that these people are merely speculating and that is about as useful as a rumor, which is worthless. That’s not to say that the amateur sleuthing could not turn up a connection to the crime. But so far, it has not.

* You may have heard reports that there were more bombs. But you should know that we cannot track where these reports started and we have no official confirmation so you should not take those reports as credible. We are calling the police to find out whether they are true and we will let you know as soon as we know.

* You may have seen the New York Post report that there were 12 victims and you may have seen it publish a picture of men with backpacks, implicating them in this crime with no justification. But you should know that this is the New York Post. Need we say more?

That is journalism. That is what every news organization and site should be doing. That they don’t is only evidence of a major journalistic opportunity, perhaps even a business unto itself: The What We *Don’t* Know News, the only news show you can really trust. It doesn’t ignore breaking news or what you’re hearing. It adds value to that flow of both information and misinformation.

On Howie Kurtz’ CNN show this weekend, Erik Wemple said that news organizations should report nothing until it is confirmed. Lauren Ashburn countered that police did not confirm even the Marathon bombings until nearly an hour after they occurred, so clearly that’s untenable. She’s right. But this is easily solved if journalists say *how* they *know* what they *know*. We know a bomb went off because we saw it and we’re showing it to you over and over and over and over again. We don’t know whether a suspect has been arrested because we didn’t see it ourselves and police haven’t told us yet and hearing it on CNN isn’t good enough.

That is journalism.
