oh yes responsibility has to be taken, someone takes a drug due to peer pressure, curiosity or whatever reason, but someone who is a drug mule, who swallows drugs , hides them in a suitcase etc, knowing these drugs will be sold to people who are, or will be come addicts because of their illegal actions carry more responsibility than the addict, your right the death sentence is wrong, it's too good for them, a life time of hard labor in Serbia will give them time to reflect on the destruction of families and life's they helped to destroy.
its funny watching immigration programs on tv, none of them are aware of the drugs hidden in their case, someone else always packed their case for them

i cant think of a valid excuse someone who swallows the drugs could have...
good the Chinese did this maybe the ultimate deterrent, death will make some people think twice or not do it at all
