//And why do we do it//
Well Canary, probably because lefty liberal (like yourself) lawyers keep finding technicalities to get round the laws we have. So they have to be tightened or made more specific.
As for mobiles, in case it has slipped your mind, technology has moved on since your day and the laws were never made for such devices, so again needed adaptation.
I think this is great news. Bange em up for as long as possible, and deport the foreigners that do it.
