"The people on the boat who were unfortunately killed, chose to attack the Israeli forces,"
There is no evidence to substantiate this claim, nor will there be as Israel (once again) has refused an independent enquiry into the incident and has said that they will hold an internal one - and find themselves 'not guilty' no doubt, as they have in the past!!!
However, there is evidence that four of the dead were killed by a single bullet to the back of the head, suggesting they were executed.
We will probably never know, so leaving the field open to your making unsubstantiated claims such as this one.
