Planning a trip? Great! Pickpockets LOVE tourists, because they are vulnerable and away from their comfort zone. Don't let them ruin your vacations. As a tourist, you are their number one target.
You've probably heard of the money belt or the pouch. I've never tried any of them, but personally, I think nothing yells "I'm a tourist!" more than a pouch under your shirt. Some say it's very effective, but I'm sure a lot of pickpockets have specialized in stealing money belts and pouches... I prefer to keep as little cash as possible when travelling. Divide and rule : don't keep your money in one single place. I can bear with the loss of a portion of my travel money, at least better than with the loss of all my vacation budget.
I think your best chance is to avoid looking like a tourist. And if it's not possible (my accent often kinda gives it away), try to look confident, to know where you are going. If you need to look at a map, do it in a store or with a wall at your back. If you feel unsafe, be unpredictable and suddenly change direction, or enter a closeby store to gather yourself and perhaps make the pickpockets lose interest in you.
The fun thing in travelling is talking to strangers and discover an other culture. I don't want you to become so paranoid that you stop having fun when travelling! Just pay attention to your surroundings and keep an eye on your valuables when engaging a conversation with a stranger.
If you have read this blog, you are now well informed about how pickpockets operate, and I'm sure you will be careful and aware. So stay away from hot spots and have a good time!
