Apparent shooting near middle school

 
People have been talking over the last couple weeks of an apparent shooting near an elementary school of a nearby town.  The individuals involved are believed to be related to the Zetas drug cartel.  Witnesses could not say what the motive for the shooting was, but the apparent sound of gunshots alarmed teachers who had been outside with children during recess.

The local radio station had been reporting on other matters and apparently started to report of the shooting, but later retracted what had been reported stating that the radio station made an error and misreported something that never actually took place.

These brazen acts may be common in other parts of Mexico, but not here.  This is the first of its kind.  Is this an indication that things may be getting worse for our relatively violent free border towns?  Various news sources suggest that it is more dangerous.  Just last year in a nearby border city, the police chief was assassinated after being on the job for less than a month and vowing to "in no part to commit corruption."  Another border town police commander nearby also experienced a similar fate just three weeks ago.  Are we headed to the likes of Ciudad Juarez or Tamaulipas where drug violence has become common place and people live in fear 24 hours a day?
