I did go and look at the video’s of crime in Cancun…. I could only find ones from 2008, 2007. I continued to read other US reports and all of them claimed Cancun, Rivera Maya, Cozumel, Tulum Playa Del Carmen are still amongst the safest places in the Caribbean. I would think there would be travel advisories from the US if it was so dangerous. When we went to PV back in 1996 there were police patrolling the streets but it was safe for the most part. I wouldn’t go now because there has been trouble as of the past few years.
If you look hard enough you can find bad thing happening but that goes for anywhere.
