Random pre-vacation thought

Now might not be such a good time to take a summer vacation to Acapulco. Apparenlty, they're having a problem with decapitations:

Authorities on Friday found two human heads in front of a state government office in the Mexican resort of Acapulco, a day after a similar grisly discovery was made outside the main entrance to City Hall.

The heads were accompanied by a note that read, "One more message, dirtbags, so that you learn to respect." They were dumped in front of the Guerrero state Finance Department where the heads of two decapitated police officers were left in April with a similar note that warned, "So that you learn to respect."
