As seen in WhatsApp videos and others, only when police chase one person, immediately those observing this are disappearing/covering with mask, etc. This shows that violations need to be dealt with with penal actions.
It is my opinion that all those violators found by police or such authorities should take photographs with violations, round them up and use them for work in covid hospitals / cleaning the roads / such works and defame them with the publishing of photos in police websites. Such persons should be herded and taken like municipal authorities chase, round them up, and take stray dogs and other animals that cause a nuisance to the public.
Even then, I do not know whether the change will come as it is human nature to say 'no' to what said by authorities 'yes'.
As an extreme step, imprisonment orders shall be given and enforced. Maybe such an extreme step will bring order in society.
