I've seen a lot of conflicting statements of safety in Colombia. While most travel websites seem to suggest the violence has gone down, and safety up, I also see that the US state travel website has reposted or updated it's travel warning about Colombia:
Violent crime is a threat throughout Colombia. Kidnapping remains a threat, although U.S. citizens are not specifically targeted. Violent political groups and other criminal organizations occasionally kidnap and hold civilians, including foreigners, for ransom.

Can someone provide any clarity on this?
