Can ‘Blue Lives Matter‘ legislation reduce attacks?

Louisiana recently became the first state to enact a "Blue Lives Matter" law, and similar legislation has been proposed in places like Florida, New York, Pennsylvania, Tennessee, and Texas. These laws have been proposed in the wake of an increase in ambush attacks on police such as in Dallas and Baton Rouge. Can laws making assaulting a police officer a hate crime actually lower the number of assaults on cops? Jim and Doug discuss the idea.
