re: #34 sagehen
Pretty sure the Orthodox CANāT carry a gun on Sabbath. They canāt even carry house keys or cash. (thereās a few Orthodox in my building; they walk downstairs on Saturday mornings, the doorman holds their keys while theyāre out for services and pushes elevator buttons for them when theyāre ready to go home.)
Carrying a weapon on Sabbath is permitted for pikuach nefesh (protection of life). This is why IDF active soldiers and reservists carry weapons everywhere they go, including on Sabbath. BTW Israel has some very strict gun laws, unlike the RW meme that everybody there is armed to the teeth.
