As a recipient of one of these letters a few years ago
I of course did not pay the 'Protection Money' but replied encouraging the firm to proceed with formal legal proceedings if they were certain that I was a liar and a thief and were willing to state this in court. I heard nothing back, big surprise.
A good long jail term for racketeering would have been better.
BTW "The Lawyer" doesn't seem to be accepting comments now
