MR GORDHAN
Something that's fairly firm, elastic, not easily porous and therefore no air would be available.  In other words it would be pointless using that to suffocate any individual.
	The second is that the necessity to have a rope and put around the blanket is to immobilise ones limbs and obviously if one is being suffocated one would resist that suffocation and it makes absolute sense to me that such a device was actually used to mobilise me but let's leave that for the record, Chairperson.  I'm quite surprised that after all the details Mr Botha remembers that one he can't remember.
