I think this would just further enrage the public and cause more societal conflict. Citizens informing on other citizens for things like not wearing a mask, being to close to someone else or being in too big of a group feels dystopian.
While politically it may be unpopular the thing is, we already have exactly that system in place in CABA for parking and traffic infringements, and we also have a toll free number to denounce quarantine violations. Numbers to denounce tax evasion, numbers to denounce general crimes, numbers to denounce noise disturbances etc. Like pretty much any society.
Frankly speaking the public needs to choose one of three options:
1. loose their basic freedoms and stay at home, loosing money in the process
2. follow rules and protocols in public spaces or pay a fine for non-compliance (or some other consequence)
3. risk infection and death of self or others
I just don’t see any magic bullet that doesn’t need some form of compromize on the part of the public. Just asking Argentines nicely to do the right thing
never works.
