Why are Israeli troops shooting little children point blank in the chest, killing them?

As they promote it...they are supposed to be getting rid of Hamas for the benefit of the Palestinian people..to free them. Then why is it I am seeing images of small children...they look as young as 3, with bullet wounds straight through their chest? It is not "accidental" shootings...you cant accidentally kill an innocent child. What were they...members of hamas? Did they throw their bottle or dummy at a troop? Also with their latest weapon they are using (that looks like a flare or firework as it rains down) - it is phosphorus which burns anything that it lands on ...therefore countless people are receiving burns that just eat away their flesh as soon as it hits. All this from the "innocent" Israelis? They are nothing but trigger happy terrorists. After all that they do, and everything is still Hamas fault. Only about 10 Israelis have died (5 were from their own friendly fire - what idiots) compared to 900 Palestinians. When are people going to stand up to these murderous, ruthless pieces of dog poo????
