Spent a couple of nights there during my travels and never looked like encountering a problem.Walked all over the place in the city and along the coastal highway. I must admit it was a few years ago but I remember the man in charge of the Carabinera at the time was given an honour because of his work with the youth and intergrating the local force to be more focused on communication with the population. He was rewarded by being the youngest ever person in the Carabinera to be promoted to the rank of Captain. There was a lot of publicity about it at the time in Antofogasta. Try and get sent to Iquique, one of the most beautiful well kept beaches and surrounding parks on the Pacific Coast of South America.
A lot of the warnings in Chile these days are based on the rallies against the education system and the unions, especially the mining unions, over work related conditions, albeit there are better than many other Latin American countries. Both being influenced by communist supporting office bearers. The young lady who started the education rallies, is now an official member of the Chilean communist party.
