Sportsmanship.....or the lack of

I don't get it.  At what point will the sports world (franchises, fans and owners) stand up and say "ENOUGH".    We have players using drugs, beating their wives and dogs, getting arrested and lo and behold...they're back in the game.  I think it started with John McEnroe and his juvenile tantrums that should have been stopped then.  It's gone on and on.  Now, France, with their soccer team storming off a field and today yet another tennis player actually spitting at fans and walking off the court.  I say ENOUGH!!  Forget fines....these sports figures make so much money that a fine is considered 'cost of doing business'.  I think that any contract player who is arrested should be FIRED!!  No ifs and or buts. Caught using illegal drugs or steroids?  FIRED!!Curse the umpire at a tennis match?  FORFEIT THE GAME!!   Maybe if we had made examples of these out of control people, the rest of them would think twice, knowing it could cost them their careers.    What are we teaching our children when these 'heroes'  never have to be reponsible for their behavior.?  Where is accountibility?   Or is the lesson if  you make enough money....you can do what you want without consequence.  Not a good lesson.....and certainly not sportsmanlike.  .
