Postal inspectors will have a busy few weeks ahead...or not. Take a report and file it, easy peasy.

I worked as a contractor for the USPS a number of years ago. And while I can attest to the fact that most postal employees are lazy, liberal, Affirmative action babies, the postal inspectors, back then at least, were hard core and took their jobs VERY SERIOUSLY. You did not want to mess with them. They would hunt you down. That may have changed, but at one time they were some of the best in the law enforcement business.
