I tried to fit bolt cutters under there..won't fit. I would have added more metal if they would.
Like I stated it won't deter someone if the have the tools and time, and don't mind a few thousand volts from my Tazer if I catch them in the act. I might even 'hose them down' with some Red Dye in my Pepper spray for identification later on.
It's not an easy life being a Thief.
