The meaning of "as well as"
In the folllowing sentence, what is the meaning of "as well as"?
"The site was chosen to protect Mr. Wilders, who has been under constant guard because of
death threats related to a long history of inflammatory comments, as well as the judge and prosecutors."
Are the judge and prosecutors to be protected as well as .Mr. Wilders? I cannot see why "as well as the judge and prosecutors." is added. It does not seem necessary.
