(2) For the purposes of this Part, a person is reckless if he or she disregards a substantial risk that the property handled is stolen, and for those purposes "substantial risk" means a risk of such a nature and degree that, having regard to the circumstances in which the person acquired the property and the extent of the information then available to him or her, its disregard involves culpability of a high degree.
