Drugs, explosives? No, its US dollars what dogs in Argentina border controls are trained tosniff for.
This has been going on for some time, since the unofficial ban on foreign currencies was imposed. The main focus of attention was the check points between Argentina and Uruguay, mostly the popular ferry services between Buenos Aires and the neighboring country. This time it was the border with Chile, where a man was arrested for trying to get into the country with 98.000 USD in cash hidden under his clothes.
Now if you want to brutally attack a senior Americantourist in downtown Buenos Aires, that you can do without a problem and even if doing so in front of a police officer the worse that will happen is that you’ll have to lose 6 hours of your day making a statement, then its back to mugging people for you. Murdering, robbing or raping people is not the kind of thing the Argentine government is worried about stopping, but those rich pigs with USD, now those they quickly throw behind bars. If they are not politicians, that is.
That’s the ironic thing about the rule of law and the WROL myth. The fact is, during periods of tyranny, the law wont be there to protect you but it will be enforced when new rules to take away your freedom are created.
