One input from a guy who knows LDS and JB for a bit. They are not pulling your leg they do care and I am sure if you have a list of places your interested in they can shed light in a big way to the safety of the sights.
Remember you stick out like a sore thumb in a different country. My wife's father grew up in Jamaica and no longer feels safe to got there so figure that one out.
They are throwing out a caution flag for good reason.
Nice to see some one close to home on here as well I hail from Burlington spent a good deal of time in Scarborough as well.
Everyone in Trinidad is touched by crime. Anyon who thinks they aren't don't know the reality of life out there. You have to be vigilant and aware of what's around you at all times. Most people that get hit seem to be foolish about their safety. That's not true all the time, but most of the time.
