Originally it was "several extremely nasty, possibly illegal, emails"...later that day it was one email, then you found a second email.
How many was it now...one, two or several? You originally wrote "several", are there more?
If not, then you lied about that.
You still haven't posted this "original" email, which you claimed to be the first in a series of "several extremely nasty, possibly illegal, emails".
The email that you posted on 12/14/17 wasn't extremely nasty, but you claimed that there were several.
Were there several more that were "extremely nasty, possibly illegal, emails" ?
When did you question Singer about the emails, and when did he deny that they were from him?
