This argument is analogous to that around witchcraft in the Middle Ages. The more you look, the more 'evidence' you will find supporting your viewpoint. The more an opponent denies it, the more 'proof' of your theory. Sheer madness...
I do think that a cop, searching my bag for cigarettes and everyone else's in a road block, coming too close and personal without mask , or clean hands, increases the chances to spread germs.
Both alcohol and cigarettes are still not illegal substances in SA , so the cops shouldn't be searching everyone for them, which will greatly lower contact.
