There have been major disruptions to our local train service recently, caused by theft of signalling cables. The scumbags responsible for this show similar absence of thought for other people's safety. The annoying thing is they'll get a hundred quid or so (if that) for the hardware, and cause £ tens of thousands of damage in the process. Its not an excuse, but I suppose increased hardship and decreasing police presence will lead to this sort of thing. I think a more proactive approach is required - cctv, patrols, etc.
