:: point of observation : the police can do things like this . whether it's entirely legal is something you'll need to hire a lawyer to discover ( and it might be worth the $ 100 + dollars just to get a consultation, because a good lawyer will quickly tell you whether there's any case here to be had ).

Looking through a mirror from different positions ( but necessarily with the point of observation restricted to the halfspace on one side of the mirror ) is like looking at the 3D mirror image of space; without further mirrors only the mirror image of the halfspace before the mirror is relevant; if there is another mirror, the mirror image of the other halfspace is too.
