There's some sound logic to what's being put forward in that link.
For example, a young mother lives in an area of a city that's being torn apart by riots and she's desperate for food for her crying baby. All of the shops in her area are boarded up and, with riots taking place on the streets, there's no hope of getting anything delivered to her apartment. So, rather than see her baby starve, she risks her life by venturing out onto the streets to try to find some food for it. She comes across a food store that's already been broken into and goes inside to fill her shopping bag with baby food. However she then gets apprehended and charged with 'looting' (which carries a 3 year prison sentence).
To me it makes sense that the charge should either be dropped altogether or, at the very least, lowered down to the 'misdemeanour' level of 'shoplifting'. As I read Spicerack's link, that's all that's being suggested by Ms Becton.
