I'm with Fred. Often times, we get email from people such as this and all too frequently, people send it along without verifying whether it's an actual threat or just a hoax. Anymore, I don't even read this sort of email

I know not everyone has the time to check to see if it's a hoax or not and wants to warn people of these things as a courtesy, but my theory is, if you have the time to read the email and then post or forward it, then you have the time to check and see if it's a hoax first
