latest round of fatal police-involved shootings — he’s laying less blame on cops and guns, and more on their choice of ammo … lead bullets made to kill.

The way Dog sees it … 20-year-old Daunte could have been taken into police custody safely if Kim Potter, the former cop who fatally shot him, was using non-lethal bullets.

As you know, Potter claims she confused her Taser and her Glock and fired one deadly round.

Dog’s already starting an initiative, called “Get The Lead Out,” to get police to swap out their lead bullets for non-lethal alternatives like pepper balls … and he tells us why cops like Potter need to train like he does.
