Yes, but not in covid-time.
So your answer is NO when adding the implicit timeframe.
FTFY.
Thank you.
Yes, but different behaviors elicit different reactions. Just like they've always been encouraged to "snitch" on other dangers, like חפץ חשוד
חפץ חשוד isn't "snitching" it's alerting to a potential perceived danger. I fully recall the photos that were circulated back in the 70s of potential booby-trapped items, such as a loaf of bread, a book, and the obvious bag. And the tag line was "אל תיגע פן תיפגע".
Some examples.
There's a huge difference, this was about teaching people to be alert to deliberate terrorist acts that were meant to be disguised and kill, whereas most people who aren't 100% adherent (or perceived as not being 100% adherent to COVID-19 rules) have no intention to hurt anyone. Case in point: back in February I knowingly ignored בידוד including visiting at risk facilities. I did that only because I knew that I do not pose any known or perceived danger (despite getting a positive PCR result a few days earlier - which I knew was false). I was subsequently officially released from בידוד once my status (antibodies) were verified.
You still haven't described people showing panic.
The snitching and the hate and attitude we've seen towards Charedim in Israel during COVID-19 times is definitely driven by panic.
