There needs to be a clear differentiation between living in the US and living in EY. Likewise living in some parts of Brooklyn and living in a tame OOT neighborhood are different, as are living in Beit Shemesh and living in a settlement.
The primary purpose of guns is to kill people, and they are VERY VERY dangerous. I’ve had gun safety and I can tell you that there is no such thing as an unloaded gun. In fact, every year many people are killed by “unloaded” guns.
So check the statistics in your area. If the odds of being the victim of violent crime or terrorism are high, then, if you have considered the danger of accidents (like your kid getting killed) then by all means get one and take the proper precautions.
And if the stats are low and you don’t need one – don’t be a fool. A gun is a bomb waiting to go off. You don’t want to take on that risk to your family just to look macho.
