The crimes in the U.S.V.I are usually on St. Croix and St. Thomas and are for the most part 3 types... Homicide do to involvement in illegal drug trade - homicide in domestic environments - there is a high incidence of domestic abuse here - not sure if its more than New York but it is heard of often so more reported perhaps - for example last week a boyfriend killed his girlfriend before trying to commit suicide himself.... this is not uncommon - not an every day event either but not uncommon. The third sadly is child abuse/molestation - a lot of it is statutory rape.... however more often than not it's young children. That's the bigger three... others are car theft, house break ins. There are a few areas that are not recommendable - and there is no reason a visitor would be there anyway - they are all residential areas... not areas you would stumble into either unless you were super lost. For the most part areas are safe, use common sense if somewhere, someone seems suspicious - be cautious - you are on vacation, this is 'paradise' but still keep your eyes open and be safe and you should have no issues.

During the night - the same dangers that are present in any city/night life scene are present - if the teens are girls you have the potential for experimenting with drinking since the drinking age is 18 years of age here in the islands so they might be able to get away with drinking - then you have young men who might try to pick up on the girls - I am sure you get the picture. On the other hand the night life areas here are Greenhouse, Duffy's, Epernay and they are safe - I would not recommend that your teens go out and wonder around unlit areas for example. But if you have responsible kids and they play it safe they will be just fine by themselves. But keep in mind the potential to get into trouble like anywhere else is also present here. If you are hesitant then I suggest perhaps you go out together - let them do their thing, you do yours - I know how teens are - just pretend you don't know them if they want their own space - and then when it's time to go everyone leaves together.

I was going to answer this but Islander has said it all. Common Sense goes a long way. Have fun and enjoy.
