A) Calling the police shut off an alarm blaring in the dead of the night is not mesira.
Source? I cost the fellow money as his car was ticketed. If that’s not being moser the mammon of a yid, then I don’t know what is. The fact is that I did not go to a Rav or Bais Din before doing so.
B) You can only kill the moser before the mesira.
I find that hard to believe. You hear enough stories about mosrim being threatened well after the fact.
C) One mustn’t kill a moser (when permissible/required) if it’ll endanger his freedom.
Source? Do you also not have to perform a bris milah on your son if it might endanger your freedom?
