if this was true, then Lebanese forces made a mistake as they thought the tree was located inside their borders, there was a fence separating the tree from the Israeli side afterall, so it isn't surprising the Lebanese side thought and acted this way.
compared to, for example, how many civilians Israeli forces murdered on international waters, this is nothing.
No one determined yet it was murder, Habibko. Jumping the gun a bit?
This case, however, had been decided already. The Lebanese army killed an Israeli soldier on Israeli soil. Period. That's a decleration of war, and murder to boot.
Why don't you consider that as a possibility. The Israelis are heartless murderers by a default, but the Lebanese soldiers did it 'by accident'?
The Lebanese soldiers can't say 'self defense', because the Israeli soldier was mowing down a tree, not sitting in a tank. They also can't claim it was an accident, because what they said is that they disagree with Israel whether this place was Israeli territory or not, and therefore decided to shoot. Couldn't they have checked with UNIFIL first? I guess not. They killed a man first and asked questions later.
You claim the Lebanese were 'mistaken' - that's not what they said. Nice you make the excuses for them. They said that in their opinion, where Israeli was is Lebanese soil, pity the UN disagrees. They don't claim it was a mistake because they realize how stupid it is - the Lebanese know where the border is.
BTW, your argument about the fence is clueless. The fence is located where it is because it can't be located exactly-exactly on the border. This area, which I know, because I've been there - isn't a flat land, there are mountains, rocks, land you can't stick a fense in, so the fense is located a few meters before the actual border. The Lebanoni army knows EXACTLY where the real border is, and they know it isn't where the fence is.
