In Singapore nothing make perfect sense when official press release to mainstream are concern.
Seriously, would those buggers with their Remingtons use No 4 for defence; I would expect at least 00 , 0 or Slug. 4 is good for fox bats and other large avian targets.
For Numero Uno, his theory is plausible given the official releases details. There is no mention which officer shot the fella, size of bullet hit, nor were the names of the person shot or arrested released. You will notice the entire PR release were controlled in a manner similar to the March event. Its like what they want you to hear only.
It is also possible the officer shooting were using high power 9mm rounds wih possible AP capabilities to achieve such a clean shot. A revolver shot would never create such a clean effect.
If this incident is true, druggies in Sinkieland is really dumb beyond words.
