Level 4 travel warning

The US State Department up-dated the travel warning for Zihuatanejo/Ixtapa to a level 4 (Do not travel too). Last year the area was level for for the State of GRO but the local Ziu/Ixtapa was level 2.
Has crime increased since last year?
My family is very concerned that MY wife and I are traveling to Ixtapa for a
6 week stay.
Really -- How dangerous is it now?

As best as I can recall, we've had a "Level 4 - Do Not Travel" designation since the days of Bush, Jr. I can only recall two violent deaths in recent years involving U.S. citizens, one who ran a checkpoint in Petatlán at some ungodly hour of the night, and the other a drunk/drugged tourist who spent the evening in a titty bar insulting its owner, who later shot him in a parking lot in Ixtapa. There've been a few car thefts, telephone extortions and house burglaries, some excessive restaurant and bar bills, and some harsh words towards a few U.S. citizens from time to time, but certainly nothing that merits the State Department's absurd travel designation.

You should invite your fearful family members to join you. They would be eternally grateful!

Our presidenta is visiting us today, and she doesn't travel with anything remotely resembling the security detail of the U.S. president. She'll probably walk a few streets and press a lot of flesh while also receiving requests and petitions from citizens.
