There have been some recent posts about the police bribes here in La Paz that have garnered some attention and, as a resident, I would like to offer a few things:
Bribes (mordidas) happen. This is seemingly unsettling for visitors. It's part of the culture and has been for decades. If you know how to deal with the situation, it's no big deal. Although I have a strong opinion on how tourists react to this, I don't aim to be inflammatory so let me just say this. Please understand that when you travel to a different country, you will be subjected to a different culture. Sometimes that means your comfort zone may be stretched a bit. Please keep an open mind and don't bash an entire city because you may have an uncomfortable encounter with a widely-accepted practice in a culture that is not your own.
I would like to make myself available to anyone who might have questions about anything here in La Paz should you be planning a visit.
