I don't want to be abusive and offensive in any way. It just sounds to me like the non-stamp rubbers are coming out either before QC, or after QC but not passing it. It would explain the remarks that the rubbers may have short livespan and eventual quality problems. If they come before QC they are just stolen and of unknown quality, if after QC but not passing - two scenarios - go out instead of destroying, or - no stamp because of bad quality, but still suitable for short-term training. Any info if DHS is supplyng some training centers with no-stamp rubbers?
I may be wrong, of course. What do you think?
