The IDF is working with Human Rights Watch to figure out what really happened in Gaza last year. There are apparently a number of cases where HRW made allegations about cases the IDF wasn't aware of, or had different versions, so the IDF is working with HRW to gain access to their sources, including Palestinians.
This is a win-win situation. If the detailed investigations exonerate the IDF, HRW will have participated in the effort and won't be able to complain. If cases of wrong-doing are identified, the IDF will learn from them, as it learns from everything it does. If anyone needs to be brought to justice, that will happen, too.
I like it.
