It's not a question of what you have access to now. It's a question of what you've been brought up with & what you chose to believe subsequently. No one believed the first scientists when they claimed the world was round. People lived in the belief it was flat, and anyone who questioned that was laughed at and in some cases murdered. When someone suddenly starts telling you, what you believed in for so long, isn't exactly fact, you will react in disbelief & anger.
You claim there is no propaganda in Israel, yet you made the false claim the victim was 'taunting' the soldiers. Either you made this up or you were fed misleading information from the 'non-biased' news.
The Irish Catholics in Northern Ireland had been saying for years that the British Army were colluding with Loyalist terrorists. These claims, for years, were instantly dismissed by the Protestant population & indeed leading figures in the British Parliament. No one believed it. Suddenly carbon fact that they were indeed colluding comes out (documents, testimonies etc.). Now, it is accepted, by in large, in mainland Britain that they did. The only people who still don't believe it is the Ulster-Scotch Protestants of N.I. People in the eye of the storm aren't necessarily the most informed & definately not the most open about the truth.
