I really hate to quibble and nit-pick, but... Having lived in Colombia for some time, my anecdotal experience does not mirror your fears.
First of all, if you are considering a country in which to live, you should really know how to spell the name of said country...
Colombia for the typical expat is no more dangerous today than any other place on the planet... Yes, there is a high incidence of death by gunshot wounds on Colombia, but this is typically in the poorest of the poor barrios in southern Bogota, Cali and Medellin... No different than Rio, Sao Paulo, Lima, San Jose, NYC or anywhere else in South / Central America... My point is that all countries in SA have the same endemic problems, Colombia gets singled out due to the narco trafficantes operating there...
Drug use is being de-criminalized in Colombia so you do not see a large incidence of drug-related crimes within the country... Yes, the FARC still control the drug export business, although their attacks on the government have subsided greatly over the last decade...
There was a time when I would not recommend Colombia as a safe destination for travel or relocation, but those days are long gone...
