Dr Eleanor Janega on Sarah Everard and the idea that we need the return to chivalry and knights in shining armour:

I am very sorry to tell you this, but those [knights saving pretty ladies] were not real. No grails were found. No Green Knights bested. Thinking this literature is indicative of actual events on the ground would be like believing that superheroes exist based on our cultural output at the moment. It just is not the case.
