As soon as I got off the bus near the Praca de Se which is in the historical part of town called Pelourihino, some Brazilian tourists came up to me to warn me to carefully watch all of my stuff because of the thieves and pickpockets that work the area. They walked me to my Galeria 13 Hostel that was just town a steep cobbled street from the San Francisco Church.
This was born out the following morning when a German woman, said that she and her friend were held up by a group of three guys and one of them put a knife to her throat. They went to the concert with no problem other than massive crowding. But then when they continued clubbing until 2AM, they ran into the robbers. She and her friend escaped by throwing them a plastic bag of Ganga and running like the wind.
In the squares and streets around the Pelourinho area where all of the clubs, restaurants, art galleries, and gift shops are, they have very bright street lights and heavy police patrols every half block. The police were never alone, but rather usually in groups of four. That kind of tells you the potential for danger in this area as well in the other tourist area, the Barra. Here is a typical group of four foot patrol police in the Barra area.
Here is the street vendor who is wearing the necklaces I bought from her.
