For one thing, it didn't happen "...in his own driveway..." as slyfox assumed, helped along by Jerry's previous message in which he mischaracterized "...YOUR driveway" as being the same as the parking lot of Massey's offices in Belfry, Ky where the altercation actually occurred. This is just plain wrong.
To me a key question is, was the ABC News crew acting lawfully? I believe they were.
Pursuant to widespread interpretation of the First Amendment, we have an established right to take pictures, both still and moving, in public areas. But this does not extend to all areas. For example, you can not take pictures in Federal courtrooms during trials because defendants' Sixth Amendment rights to a fair trial outweigh the First Amendment.
A private property might ban photography, however, even if it is open to the public. For example, a store, museum, theater, etc. could ban photography. But if there is no specific ban in place, and if you or a news agency are just taking pictures of publicly available images, then IMO you are within your rights.
If you wish to argue that Massey's parking lot was not a public area for the sake of this discussion, then you will likely be defeated by
precedent, unless there was something there such as signs that made clear that photography was prohibited.
And so it seems the ABC News crew was acting legally within their Constitutional rights. But in any case the Massey parking lot is not the same at all as "...YOUR driveway". And if Blankenship was not provoked by the ABC News crew in a manner that somehow justified his attack and threat (they smashed him in the face with the camera, etc.), he might be guilty of assault.
Here is a video clip that includes the footage in question. And
