Another report from Noonsite– Venezuela, Orinoco Delta: Two Dutch Cruising Boats Suffer Armed Robbery
I tend to believe that we are seeing more reporting of incidents lately rather than an upsurge in crime. Although, it is possible both events (more reporting and more incidents) is happening.
There is also more discussion in various forums, although you need to be able to discern the facts with a bit of research after reading many of the posts.
