Your post is misleading. 

Mexico's total number of murders may be the second highest in the world, but expressed as the standard 'per 100,000' it is far from second.  Yes, the Reuters report said population numbers for countries 'in armed conflict lack reliable population data', but Mexico's 'drug war' is not like Syria's conflict.  Population data for Mexico will be reliable. 

Mexico's 'intentional homicide' rate is 15.7 per 100,000.  In comparison here are some other numbers;

Belize 34.4
US Virgin Islands 52.6
Puerto Rico 18.5
Saint Kitts and Nevis 33.6
Saint Lucia 21.6
Jamaica 36.1
Bahamas 29.8

and one of my favorite places

Cuba 4.2

I was in Mexico just before Christmas and never once felt in danger.  When traveling anywhere common sense has to prevail.  Yes, Mexico has a drug 'war' going on, but this is occurring only in certain areas of the country. These areas are well known, avoid them.
