Heh... from my office window in past work offices I often see people (of all kinds) filch other peoples' left luggage and suitcases. They see it hang around it and walk off with it. I even watched a guy stack things into a taxi and a scrote peeled a suitcase off while it was stopped at lights.
Aside from this being dangerous and criminal, as bombs or drugs etc maybe found and Manchester has those dog drug squads all over. You may not want to do this in Hong Kong s not for the first time a body has been found in a suitcase by the side of the road. Murders etc are comparatively rare but this kind of thing happens now and again. As recently as described here.
This probably explains why my dad always buys a new suitcase for each and every trip and never allows people to borrow his....crap he's got my red ones.... bastard...
You can bet your top dollar it was gang related or somebody who owed a shit load of debt...what does this teach us? Loan sharks are to be avoided! (Loan sharks are those who charge more than 80% APR IIRC) as they will go after your family, friends and other completely unconnected people to pay your loans.
