I realized that this post was super boring. So, I´m going to add some stuff to it. One, I met an owner of 3 buses yesterday (Kiva client). He said he pays between 3,000-4000Q weekly to the extortionists (so times my estimate by 30).
Another interesting conversation I had was that there are 150 registered private security firms in Guatemala (and a number of registered ones). Private security outnumbers police 5 to 1.
