Who knows what Chinese sentencing is like? I'm going to assume that it's not much fun compared to most other places.
A mate of mine stole electricity from his local motorway lights to power his weed growing in a buried shipping container. They seemed more pissed off about the rerouting of power than the drugs. I guess it has the possibility to wreak quite a bit of havoc over a wide area if you mess the job up.
I get the hint that mining with dodgy power is quite a big thing in China.
