It's also important to consider when what you are seeing could be justified?

Did they perhaps just hide their weapons in a built-up area and the IDF was following them until they were in the open so they reduce the risk of collateral damage?

Or is this a case of poor discipline from the IDF, who decided to hit them because they were military age males traveling in a group?

Based on the video alone, either could be true.

A good rule to follow is that both sides are lying and when they are not, they are trying to deceive.
