Same as everyone else. Unfortunately, there may be some people who fall for this, as it does sound quite threatening. I wonder if the phrase "local cops" is by design, targeting the disenfranchised sector of society. For this section of the population, that term may resonate with them and push them into unwise action. I tried to contact the IRS to report the scam and hopefully have legal action be taken, but that was a bust.
Received a call from this number this morning with the recorded message as described by Erin (prior post). I just ignored it and have blocked the number.
