Would someone please explain its meaning? Also, what's the antecedent of 'which'?
In his Commentaries on the Laws of England, William Blackstone contended that the distinction between private wrongs and crimes was:
... As if I detain a field from another man, to which the law has given him a right, this is a civil injury, and not a crime; for here only the right of an individual is concerned, and it is immaterial to the public, which of us is in possession of the land: but treason, murder and robbery are properly marked among crimes; since besides the injury done to individuals, they strike at the very being of society; which cannot possibly subsist, where actions of this sort are suffered to escape with impunity.
