Of all of the crimes which would destabilize society if they were to be legalized, vigilantism may well be the most attractive. Living as many of us do in a society where various constitutional restrictions keep the police from jailing anyone who looks at them funny (for now, at least), it can be frustrating for anyone with a strong sense of right and wrong to ever see criminals going unpunished for their crimes. Obviously there are logistical problems that keep summary execution from being a practical solution to the world's crime problems, most of them in the area of misidentification and misunderstanding.
