Carrying a Gun on Shabbos
Question:
If someone is working in a Jewish institution and for security reasons carries a gun, is it permissible to carry it on Shabbos as well?
Answer:
If there is concern about a possible threat which would justify carrying a gun on Shabbos, even if it is Muktza or there is no Eiruv, a local Rav with an understanding of the prevalent conditions must be consulted to determine whether the current threat is significant enough to justify carrying a gun on Shabbos or not.
