I seem to have hit a nerve. Donald Trump today sent an open letter to me to the media (a reporter sent it on to me - somehow I was missed off the distribution list).
He seems upset that I have pointed to the issue of locked gates around the periphery of the estate (see photos and map) and has resorted to personal abuse in an attempt to deflect attention away from the issue.
The advice that anyone in public life faced with abusive correspondence is usually to ignore it.
Update 18:36 - now received by email from the Trump Organisation direct.
Email to reporters time stamped at 12:56.
How to determine order of authorship in an academic paper - This is the sort of footnote I like.
