I think anyone who can look at the situation and understands history can guess what the touchstone for riots that would require Martial Law will be. I am not that big of a glutton for punishment to "say it out loud" on an open forum on the internet, but riots that would make the LA rodney king riot look like a fight at kindergarten recess could be set off by someone popular among the poor minorities being attacked. Global warming might be a reality then, as the country is engulfed in the flames of the frustrated masses demanding "their share". This could get really ugly here before its all done.
As far as Mexico goes, I just met a girl who's family was kidnapped and robbed and abandoned in the desert during the last Baja offroad race. Its never been 100%safe down there, but now might be a time to consider doing some visiting with family and friends up north, like, say, Canada.
