A friend of mine held a job as a reporter for years with nothing but a BA in psych. He's now a lawyer and tells me that no particular background or training is required to be a reporter. According to him, Brock does not know what he's talking about.
Journalism is not a field with a license or something.
If you can get hired, you get hired. Usually you must have past experience, but you have to start somewhere without experience obviously.
