The crime was not apparently a vendetta against the airline, although all members of the crew have been relocated to another, undisclosed hotel for safety reasons. According to the article, there was no security breach at the hotel. However, clearly some kind of 'laxness' must be at the root of the violation, given that not only was the criminal able to enter into the area of the hotel where guests remained, but no one was alerted by the sounds of the violent crime, which must have...

Hopefully, the Mexican police will be aggressive in finding evidence linking the suspect to the crime. The evidence seems to be strong, because the suspect had the belongings of the victim and evidence of his presence in the hotel has been found on surveillance tapes. But the issue of the high crime rate in Mexico will not 'go away,' regardless of the outcome, and tourism in Mexico City will decline sharply if there is not evidence that the police are beginning to take violence seriously.
