And they could just as easily have cutting pliers with them for your cable, or bolt cutters for your padlock.

I'm still shuddering at the thought, but arriving at work on Monday afternoon this week, I found a fully-charged cordless angle grinder abandoned in the parking lot. I never thought I'd see the day, but now I can add, that someone could just as easily have an angle grinder with them to slice off your D (or U) lock.

At some point you just have to say "good enough". We all get to choose that point for ourselves.

I don't know what I'm going to do with a nice Ryobi cordless angle grinder, but I now own one.
