1-) The news says the guy was armed. But no mention of what kind of the arm. 2-) IDF simply reports that he was NOT AT THE FENCE, but near the fence. And over the suspicion they start shooting. 3-) In many cases we found out that these terrorists killed by IDF are mostly shephards, farmers, fishermen, curious children, rarely a Hamas militia. 4-) Gazans and Hamas people has every right to walk around the border as long as they don't infiltrate or attack. Almost none of the cases, this happened. Experience shows that IDF suspects anyone, Because everyone has "two arms". And kills.
