Like Connie above, I didn't answer. However, given that no message was left and calls are being reported by others, I am confident this was another scammer. The number is now blocked.
Claimed to be a charity asking for money for a "police officer death benefit" and "tougher penalties against harsh criminals".
Well, non-profit charities can't lobby for "tougher penalties" because that's illegal and departments carry life insurance on their officers by law.
SCAM! HANG UP! SEND NO MONEY!
