I’ve visited there as well and even though this might not have been Cartel behavior, tourists are preyed upon every day regardless of where you are in Mexico. Last year someone tried to pickpocket me in Tequila. Even relatives of mine who live there advise against wearing jewelry, and straying away from tourist spots. The cops there aren’t your friend.
I have traveled the world and have traveled in countries during States of Emergency there.....that said, Mexico is OFF of my list.
Anyone who thinks it is safe is in serious denial and needs to reassess their objectivity.
