One of the (many) potential downsides of downing a half a bottle of scotch after work in your typical evening at home is that you may become less capable of distinguishing the line between a consensual dominant/submissive relationship with a partner, on the one hand, and something far less legal.
Which may result, as here, in you spending the rest of your life in prison.
(Though maybe the defendant here knew what he was doing all along.)
