Again I'm very late in getting to the news.
Personally I think an occasional riot is a sign of a healthy democracy, it's not that there aren't better ways to solve our grievances, but if the problem is with the government then often the normal channels cannot be used to fix them. When all other options have been exhausted sometimes a riot is the only thing left, other times, like the ones in Greece are reactions to a very specific incident but are always caused by underlying problems. The LA riots weren't about Rodney King, that was simply the last straw that broke the camels back. These riots in Greece were about Alexander Grigoropoulos, his death was simply one injustice more than the people could deal with.
Heres some pretty amazing pictures from those riots.
