I am afraid to ask about how you learned about police interrogation rooms. A school trip no doubt :)
A one way window actually isn't one way at all. It is just darker on the other side. The light from the dark side is just flooded out and overwhelmed by the light reflecting from your side.
To make a one way mirror, just 'sprinkle' silver atoms onto glass so that it is only half coated on average. Photons then have a 50/50 chance of either passing through or getting reflected.
Pro-tip: never use one way mirrors for your bedroom windows.
