Also, the re-emitted photons aren't bounced back in the same direction from whence the originals came. If they were, a person could look at a mirror from any angle and still see his or her image. Reflected photon(s) will follow a path that's equal in incidence to the optic normal but opposite in direction to the incoming photon(s).
Sure they do, but only if the angle of incidence equals zero. One of the principles behind a LASER.
