What's to investigate that hasn't already been reported for years?
Hamas has fired 10's of thousands of rockets at Israel from palistinian homes since 2005.
Built tunnels for the purpose of terrorism against Israel.
Kidnapped Israeli kids and killed them.
The losses to the palastinians in terms of lives and property is deplorable, but the palastinians go along with the program instead of turning on Hamas, and running them out of their country.
There is a lesson to Americans in all this, [Don't let anybody take your guns so you would be defenseless]
