I was reading about the murder rate on St Thomas and it is very high but I also read on some websites by locals that those murders and crimes are mainly if you get involved with drugs or just the wrong people. I was wondering if this was true or not?
It's called being in the wrong place at the wrong time and yes, they are mainly due to drugs. Back street is just one of those areas that tourist and locals alike shouldn't go.
Before I went I was told to go where lots of tourists go, only be out during daylight, and when the cruise ships reboard, go inside and stay there. It's worth the trip but be cautious. Drugs are hidden in plain sight but there is safety in numbers and in daylight, together.
"only be out during daylight"
Sorry but that is absolute nonsense. There is a very active nightlife on St Thomas enjoyed by both travelers and locals. The safety rules on island are pretty much the same as every place else: avoid dark alleys, don't go looking for drugs, and use common sense.
