From Wikipedia, the free encyclopedia

The medical idea of (grievous) bodily harm is more specific than legal ideas of assault or violence in general, and distinct from property damage.

It refers to lasting harm done to the body, human or otherwise, although in its legal sense it is exclusively defined as lasting harm done to living human beings. It deliberately does not admit social, ideological, or psychological concepts of violence, but admits forms of property damage that a reasonable person would consider likely to cause lasting bodily harm; e.g., turning off a pacemaker or respirator, or ejecting someone into a cold wilderness in winter with no other source of shelter.

Police actions are usually defined as those motivated by reducing bodily harm to "innocent" victims, even if violence or property damage is required to do so. The definition of "innocent" is of course dependent on an ideology or due process of law. In general, police also seek to reduce bodily harm done to suspects as well, although this is a lesser concern, much less in some societies.

Doing bodily harm outside the legal process of a given society is usually considered crime, war, or "terrorism", a 20th century term describing various styles of guerrilla and asymmetric warfare. In general, public opinion in the developed world does not support definitions of "war" or "terrorism" that do not refer directly to doing of bodily harm.

Systematically reducing, channelling, or eliminating deliberate bodily harm from human public relationships is a major focus of political science.

Reduction of accidental bodily harm is a function of engineering that rises to special prominence in safety engineering and biomedical engineering.
