They sell right angle battery powered grinders, no lock or cable can withstand a cut-off wheel.
Mine are locked, and in a locked and alarmed shop that has 2 out of 5 cameras facing it which record to a 1TB hard drive hidden in my house. Good luck!!
My driveway is fairly long, but my camera still caught the guy who smashed in my mailbox.
He got bagged and a HUGE fine as it's a federal offense; Lucky he didn't get sent to prison!!
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
