You can practice safety in Los Cabos by booking a hotel in Cabo in a safe area, such as the beach or Cabo Marina. While big cities, such as Mexico City, have the worst reputation for criminal and criminal activities, there is definitely crime in Cabo (and in all of Mexico's tourist towns).
The media painted this horrible image of Mexico and I always wondered if it was safe to travel to Mexico. I thought Mexico was dangerous, the cartel would kill me, kidnap me and hold me for ransom because of the US travel warning to Mexico. I will be continuously updating the Mexico Travel Warning and Cancun Travel Warning articles, so you will always find updated information so you can plan your vacation without worrying about your safety.
