Why bother?
Why bother emailing a professor after you're specifically told not to?
Why bother telling that professor that you're emailing between private accounts so that there's no public record?
Why bother telling an academic advisor that you're specifically trying to circumvent OPRA?
Why bother setting up a clandestine meeting with a professor at a location 15 miles from campus and intentionally wearing non-Rutgers attire so you won't be recognized?
Desperation. Pure and simple.
But you didn't answer the question. Why bother doing everything you stated IF he knew Barnwell was under investigation?
