I'm surprised the nation has held together as well as it has since the 'Dirty War':
http://www4.cnn.com/WORLD/9803/02/argentina.dirty.war/I recall a 'mini riot' that took place during a soccer match between a military academy and a local school - the school players taunted the military players - on tv. Nothing else happened and the game was played.
I don't recall who won the soccer game. Pretty nasty business; kidnapping, robbing, torturing, raping and murdering everyone you didn't like and under cover of authority.
