Just called. Answered. Man on other end said hello in a questionable tone. I asked how I could help him and he hung up without a word. Number showed up on caller ID, not other identifying information.
They called on a Saturday afternoon. The caller said his name was John and he was calling from the American Sheriff Association (or something like that). They were trying to raise money to support the families of law enforcement officers killed in the line of duty. He asked for a donation. When I suggested he send something through the mail, he said they would, but they had better success if they spoke to people first. I hung up because it didn't smell right.
