Just in time for Valentine's Day comes The Legal Kiss, a new book authored by Texas Tech law professor Vickie Sutton. From the back cover:
Did you ever think that a kiss was just a kiss?
Anything that has stirred the emotions as much as the kiss, would almost certainly be something that civil society would demand to be controlled! Indeed, throughout history from the fateful kiss of betrayal by Judas in the Garden of Gethsemane leading to the most famous trial of human history, to 1019 when a kiss was required by law for the transfer of property, to the ban in 1439 by King Henry VI to avoid passing along the Black Death, to the 1500s when the “kiss of peace” was required for all peace agreements in Spain — law has tried to harness this force of nature, through prohibiting the kiss or requiring one! The Legal Kiss is a light-hearted look at the law that has developed throughout time to harness the power of the kiss.
