I kid you not, that's what Walker said a couple of weeks ago:
Walker said too much attention is paid to the weapon in such shootings and cited a recent case as an example: "We just had someone last week in Neenah near a school kill someone with a bow and arrow."
As Politifact points outs, not only was there no bow and arrow killing in Neenah, but nobody was injured. And the incident in question didn't even happen anywhere near a school.
As usual, though, the myopic Politifact zeroes in on the exact details of Walker's point, but fail to address the larger (and more absurd) point that Walker is making: That bow and arrows (or anything else) are in the same category of deadly force as guns when it comes to mass killings.
