I think I would have run after the scumbag, I LOATHE thieves.
I caught a scumbag trying to ripoff my old rusty MTB out of my backyard (!) a foot from my door (it was locked to a pole) he was sawing at it with garden shears he had stolen from someone else. My dog went hysterical barking so I came running and saw the scumbag. He ran and I went tearing off after him, screaming for him to come and face me so I could beat the **** out of him. I screamed a bunch of things, none of which I can repeat here. I called the cops when I calmed down, too.
I am sure I would have done my best to clean that scumbag's clock garden shears or no. Turns otu he was also peeping in my neighbour's basement windows and her teenagers saw him doing it.
