This Is How Stupid And Horrible People Have Become Thanks To COVID-19

A silent lady was being filmed harassing a mother and her child for apparently not wearing a mask during covid-19. The lady who has absolutely no right to be advising nor recording the lady especially with a baby (which is illegal) appears to be following her and just being a nuisance.

Why do people feel the need to interfere with others unless it was something serious?
Why do they think that they are superior and want to just harass people for the sake of feeling like they are right. Point being over here, is that the lady has no right to be advising anyone over wearing a mask. Wearing a mask will not 100% protect you the same way being outside will not protect you and she's not the covid police if it were truly a matter or seriousness (which it is not).

People should get involved if the situation was indeed serious and was of concern to someone who is vulnerable.
