Another thing, any civilian carrying any kind of weapon is considered a militar target. The story of David and Goliah is pretty different from this situation, it isn't impossible to to hit another human with a stone killing him, now when you try to throw a stone at a moving tank, what are the odds of damaging/killing the tank?

Only God Can Judge Me
الله فقط يمكنه محاكمتي

I am you and you are me, if you love i love, if you suffer i suffer
أنا أنت, و أنت أنا, إذا أحببت نفسك أحببت نفسي, إذا عانيتَ عانيتُ
