Some proactive measures that can reduce someone's risk of danger or assault could be maybe if the person who is trying to keep from danger stays off the streets or they make a group of friends. Then they have less of a chance of getting into violence or assualt (Even though no matter what it is very difficult to prevent violence because it can happen at any time)
