I stand corrected, you weren't being pedantic at all. I guess all those people lined up outside the bank, ready to riot, were waiting for the government to give them their money back.
To quote the Wikipedia[1] article on the riots:
"The uprising was a predominantly middle-class uprising against the government of President Fernando de la Rúa, who had failed to contain the economic crisis that was going through its third year of recession".
"The unrest started when Economy Minister Domingo Cavallo introduced restrictions to the withdrawal of cash from bank deposits, intending to stop the draining of deposits that had been taking place throughout 2001 and had reached the point where 25% of all the money in the banks had been withdrawn." People had were previously gradually withdrawing money over time.; no 'bank run' had occurred. The Corralito occurred, which among other political factors lead sections of the populace to riot.
