Death Threats!
Does anybody know how almost 100% of the people who send death threats avoid detection and arrest?
Death threats by phone and Internet are completely out of the question, unless you are an electronics expert or software expert.
Death threats by US mail or private carriers are high risk because collection offices are always under video surveillance, and most US mailboxes are in commercial areas where many private businesses also have 24 hour video surveillance.
Bottom Line - I think almost 100% of alleged death threats are completely bogus.
