It is important that every security personnel have the ability to protect themselves because danger is not a farce.
The teaching clarifies that killing someone during self-defense is not seen or taken as murder, because it was not deliberate but was needed for protection.
But this does not give us the right to behave carelessly.
The focus should be on preventing the damage not being the first to attack.
It would be better to disarm the person coming to attack, for example, for protection you can aim a shot at an area where it would not kill him.
This teaching stresses on being wise, responsible and cautious.
The instruction is obvious: practice self defense when necessary but in cautious and disciplined manner, depending solely on God's direction and your skill.
Being safe and wise is very important.Amen.
