What are you accomplishing by repeating this at the top of your lungs? If they did send you the emails in question, the g-men are the ones you should be talking to(good luck on smartt's extradition, btw.). Until there's conclusive proof that it was or wasn't them, this is pointless and if you fear for your safety I'm not sure why you're choosing to remain around the people who threatened you.

There's also the very real chance that when you gave your email address someone else sent you them, and smartt and monkey are logical choices if you're going to impersonate someone that already proved successful at driving you bananas. Was it a free addy like yahoo? when was the account created if so...

Honestly, I'm inclined to believe both of them are innocent on this one...even if you did recieve those pictures. There are usually 4 anonymous readers for every registered one and statistically you're going to find some who don't like black people very much.
