Some guy calling from "US Deputy Sheriff's Association".  Said that they needed money for bulletproof vests and officers lost in the line of duty.  I asked them if they could send some info in writing.  Guy said that he needed a pledge from me before he could send me some materials by mail.  I said that I'll pledge something as soon as I get something in writing.  Guy said "ok, thank you" and hung up.

Sounds like a scam to me.  Oh, yeah, Stranger, let me give you my credit card number so you can take all of my hard-earned money out of my account!

No thanks!!
