"... You've got to stand for something, or you'll fall for anything ..."

All proper (proprietary) behavior, and therefore all moral behavior, recognizes and respect the rights of owners over their properties.

All improper (boundary-violating) behavior and hence all immoral and criminal behavior is a kind of claim-jump, and introduces a conflict over the rightful control of a property.

Later we shall further examine crime in the context of what it means to the principles of liberty and freedom. 

For now, suffice it to say that a crime occurs not because of what happens to a piece of property, but because of what happens to the owner of a piece of property when his will is thwarted or infringed upon with respect to something he or she owns.
