For some things, defining the "victim" is easy. Someone who's injured, murdered, has their property broken by another, is a victim.

For some things, it's not so easy. In the Duke Lacrosse case, for instance, all charges have now been dropped. That the accuser is a victim - many times over, and having a horrible life, to which she has doubtless contributed but that is likely not all her fault - is certain. It now appears equally certain that the three Lacrosse players, as well as the team and its coach (affected by having their season cancelled and a forced resignation), were all victims too - of a racist and overzealous prosecutor who sought to use the case for political gain. Nifong, the prosecutor, will likely be disbarred in June for misconduct, and civil lawsuits over his behavior are pending. (The charges against Nifong are available here. They're pretty serious.)

In the case of crimes when the perpetrator isn't known, entire communities can become victimized as suspicion causes people to become seclusive and suspicious of their neighbors. This is especially true in the case of gruesome cases, even if a perpetrator is later possibly caught.

A number of people are victims of the crimes of others - by being convicted as look-alikes or people with similar names.

Plenty of people are being victimized by the ongoing question of climate change, whether humans cause it, and a ton of junk science - the idea that ethanol can be the future, for instance - that's pushed as a "solution" while it in reality, it just makes for more problems. The latest is this "carbon-neutral" stuff that's being pushed by people... who fly around in jets all day, run motorcades of a dozen or more cars, and have mansions that could house 200 people in which only 2 live.

TIME has an interesting piece on some odd victims of violent/brutal/sickening crimes: the juries who have to look at the evidence for days but, unlike the police and prosecutors and lab workers and court employees, are given no counseling to help cope with what they're seeing.

A lot of victims to go around.
