Liberty Website Reports USPS Worker Discards Mail...what's the point?

How does the libertarian brain work?

OK, below is a snip from one of these libertarian people's websites where we can see them report an incident during which someone working for the US Postal Service in (I'm sure) violation of postal regulations, apparently discarded some mail I assume rather than deliver it during the remainder of the shift...

So these libertarians report:

A USPS worker was recorded throwing mail into a dumpster in Bond Hill, Ohio last week. The female worker is show tossing the letters, paychecks and notices into the trash and could face federal charges for the crime. 

“This is clearly unacceptable behavior that does not reflect the efforts of the thousands of professional, dedicated carriers in our workforce,” USPS spokesman David Van Allen said.

That's all the post reports, so what is the point here from these libertarians?

Libertarians are by definition anti-authority, here it is right from wiki:

While libertarians share a skepticism of authority...

So what prevents this postal worker from throwing out the mail other than authority?

If a supervisor was along for the ride that day, do we think that this worker would have pulled over to throw out the mail?

Of course not (unless the supervisor was also a libertarian I suppose...), so this postal worker simply acted in libertarian fashion, i.e. could give a shit about anyone else, IGNORED AUTHORITY, and simply pulled over and threw out the mail.

So what is the libertarian point here?  Seems like something right out of the libertarian playbook...  I just don't get how the libertarian brain works... I suppose they could have been applauding the postal worker?

Hard to get these people...
