As others have said - this isn't Disneyland
Real, working soldiers, doing real, soldier stuff - in those costumes?
Are you sure about the Disneyland thing?

And as for 'the guards are working'?
They are clearly confused about what their job entails.
And there are clearly some very deluded people here who know nothing about security.
If they are supposed to be on the watch for people trying to break into the Tower, maybe a sign they are on the ball would be to watch where they are going and notice what is directly in front of them before tripping over it/trampling on it?
Who conducts a security operation by marching in a straight line on a predictable route, at a predictable time?
A lot of MNers can see nothing wrong with this picture, apparently.
The royal properties have actual security that is not visible to the public.
The Guardsmen are there to provide a daily spectacle for the benefit of tourists, to generate good PR for the Monarch, and to foster an image of England as some quaint, tradition-soaked place that time has passed by, and they failed miserably in that task.
