If a wireless carrier hired you to do a report, how can you remain unbiased in your reporting?

We’re hired by carriers, by landlords, and occasionally by cities and private individuals.  As engineers, we deal with the facts as we know them, and any registered Professional Engineer would provide the same factual information.  Our job is to project or measure RF power density levels and to compare them with the standards.  Our computers don’t know who the client is when we’re calculating projected levels, and our calibrated meters don’t know who the client is when we’re measuring RF levels.  The numbers are what they are.
