I am waiting for just one thing before I can drop my tag on his profile, and if it hasn't been created yet at that time, I will personally create a trust flag as well.
What type of trust flag are you thinking about?
I am surprised about the behavior of the rest of the DT users. I don't remember seeing them being this silent after presenting solid evidence in front of them.
He already has 4 red tags, what else do you want? I would have tagged him but I think 4 is enough and more will probably be added over time. I don't think mine is needed.
