1. The security fence is placed tens of meters in Israeli territory, partially to ensure that Israel can keep the far side of the fence from being over grown by vegitation for hizballa terrorists to hide behind like they did when they invaded Israel and killed 2 Israeli soldiers a few years back (stealing their bodies in the process). 2. The officer who was killed was a few hundred meters from the security fence IN ISRAEL in a permanently manned position. He was shot by snipers who could not have had any confusion that he was in Israel. 3. Lebanese civilians (and hizballa terrorists in civilian clothes) come up to the border all the time, no one gets shot. 4. Please provide evidence of your claims that israel gournd forces "routinely cross the border". That's just a lie. 5. Israel and Lebanon are and have been in a state of war since 1948. Lebanon also hosts numerous terror organizations and in particular Hizballa who are bent on the annihilation of Israel and extermination of its Jewish population. As far as I'm concerned, overflights to collect intelligence to prevent the next terror attack make perfect sense. If Lebanon would disarm the terror organizations and show that their territory will not be used to attack Israel, I'm certain the overflights would cease. Unfortunately it appears that rather than Lebanon taking control of Hizballa, Hizballa is taking control of Lebanon.
