You're certainly spot on in depicting the brutal reality that can await Westerners travelling overseas - one need only look at the Australian who stole a barcoaster in Thailand for an example closer to home (luckily that had a happy ending).
But your absolute lack of condemnation of this disgusting disregard for human rights disturbs me somewhat given that you are a teacher. It's yet one more horrible black mark on China's human rights record.
And just in case anybody was wondering, China doesn't just execute people for drug smuggling - it also executes them for sedition (e.g. promoting democracy) and tax evasion. In fact, to that end it has a corps of mobile
death vans which are equipped to give the death penalty on the spot.
