My back hurts, where's my doe spray?

I follow the PGA barely enough to know what I am talking about.  But that's all it takes.  Besides, I watched the entire Masters Cup this year and I'm pretty sure that makes me a professional golfer.  I can tell you who might not be a professional golfer for much longer.  Vijay Singh.  He was having a hard time keeping up with some of the younger players on the Tour and therefore it was time for a change.  This guy was literally quoted as saying he was "looking forward to some change in my body."  This after he tested positive for deer antler chemicals.  Mr. Singh didn't use any old steroid, he went for the good stuff.  Deer antlers, which purportedly have regenerative capabilities, were going to give him his zeal back.  This Post isn't even about how deplorable it is to take performance enhancing drugs.  Immediately after the results came back from Vijay's tests, the media laid into him.  Rightfully so some might say.  The substance was, at that time, on the Tours banned substances list.  However, the Tour decided to do some follow-up.  It sent the samples to the World Anti-Doping Agency to get more information.  Turns out, the levels in the chemical were so minute, the Tour subsequently removed the substance from its banned list.  The Tour released him from any wrongdoing and waived all his fines.  Vijay sued immediately thereafter.  Sued.  He was guilty of using a substance that was banned at the time, but then once it was deemed not banned, he sues.  Uh...  Do what now?  In the legal world, when something is deemed an illegal act after someone commits the offense, it is ex post facto (and you cannot be charged with the crime).  But when you sue after you were found guilty of the offense that WAS illegal at the time and is now not illegal, its called stupidity.  Your name was dragged through the mud because you are a public figure whom some children (and adults) look up to and you did something terrible.  Your embarrassment is warranted.  When your name was cleared that should have been the end of it, but no.  Now, instead of things dying down and you moving on, you decide to make it worse.  Pure geniusness.
