§ V. On Recourse, or on the Receiver, or the One Furnishing Recourse; You Will Hold These Things:

685.
      1. A receiver, namely one who knowingly and freely furnishes security to a robber, is held concerning the damages thence arising. For thus he efficaciously and unjustly determines, or makes firmer, the will of the thief in the proposal either of stealing, or of not restoring, or of stealing again.
