I write from experience. Sometimes from direct experience, sometimes using experience to interpret the news and the impact of PR on the news. When writing from direct experience about specific situations, I will change/omit names of people and firms in order to focus on the substance of the discussion and protect client confidentiality. (And not land my ass in court.) Interpretations are just that. I do my best to support them with solid examples, but ultimately, they are just opinions and views of the facts, not facts themselves.
