The problem with our media is not that they are corrupt it's that they are torn between providing a news service as well as some entertainment value, even our largest city can't sustain seperate tabloid daily papers as well as a seperate strictly "news" type paper, hence we get the herald which really is just a crossover. Even our TV news is tailored towards entertainment content, blame it on our small population base not the media owners.
And remember we have freedom of speech here, these guys are just putting forward their version, wether they act as puppets of someone else or not doesn't really matter (and o'reilly doesn't)the fact is they do it because the want to and like it.
Back to the topic, i agree oportunist more aptley decribes him, hopefully he is forgotten about very quickly by the general public but i hope that experts in behavioural psychology learn something from him to prevent it happening again in other people.
