From a Guardian article I just read:

"A total of 6,500 officers will be on duty at G7, with all 43 police forces in England and Wales sending personnel."

Also, that Crowley house pic is from his house in Inverness, Scotland (700 miles away) that burned down Christmas 2015. There is a small dilapidated shack type house that Crowley owned in West Cornwall.
