Not getting drunk at bars likely proactively addresses a significant portion of issues.
Second, if you are coming from the USA or many other fairly high personal crime countries there are many places you are much safer while traveling. If you are coming from Japan, Singapore, Scandinavia you probably are much more likely to be the victim of crime than at home.
If you are not drunk the most likely crime is theft, while not good, it is much better than being attacked in my opinion...
The biggest concern in a new environment is that you don't pick up on the clues of danger that you would in your home environment.
