To be fair, the officer sees the glint of a lens in a window.

Is it a camera, granny’s eyeglasses, or a rifle scope?

It is prudent for him to get a good look through his own scope and rule out or respond to the threat.

Please cite the law which allows the police to go down a street and 'check' every person and house.
