Not all crime in DC is violent but it's still important to know whats going on so you can protect yourself against it. Crimes of opportunity in a city with DC's wealth abound.

Stay apprised of current non-violent trends to help guide your decisions for your upcoming plans, whether they be short term (a night out with friends) or more permanent (securing housing).
