Just a note on law: you can legally take a picture in the USA of a street scene with a crowd in it without a release, but if you are highlighting any individual in the picture, you should get a release from that individual before publicizing the picture. This is particularly true if you are attributing any negative quality to the individual (i.e. subject to ridicule). There are obviously gray areas, and exceptions (for example, a "celebrity" does not have the same protections as a "common person"), but this is the law as I understand it (I am happy to be corrected).
I don't know all the issues in this case, but it appears that the twitters played a big role. I must admit I found the Opie and Anthony show as an example of what is wrong with the current USA and I am happy to have one of them "overstep" the line and be fired. But in any case, it seems to me that they were hired because the types of statements they make increased the number of people who tuned in, and they therefore can be fired whenever the types of statements they make is likely to result in losses in the number of people who tune in. Almost all contracts with public celebrities make it clear that anything the individual does in their own lives that significantly reduce the value of "the brand" (their public image) would allow them to be fired. This is different from an auto body welder who joins the Communist party or who utters racist remarks: these things do not reduce the value of his "brand," his welding.
