Did not coin that phrase, but still cannot find the person who did.
Anyway, over the past few weeks someone has done a lot of this San Francisco.
No one knows who has done this or why. The presence of the spike through the bat technically makes this a prohibited lethal weapon. See http://www.sfgate.com/bayarea/article/Spiked-baseball-bats-left-around-SF-6661160.php for more details. So far, about 30 have been reported in various neighborhoods, so someone definitely wants to make some sort of statement. Possibly political, but until we receive some sort of communication…shrug.
