Actually, this could be a good news story if the Family was far sighted enough to kill ALL the "Police".
Effective Palestinian Violence against Palestinian Authorities and Hamas will solve the problem with Hamas and Hamas terrorism.
The one further necessary step is non-violence toward Jews and Israel to secure a peace.
Then the Palestinians will have fixed their own problem.
There are no innocent civilian Palestinians; there are only those who are Hamas fighters, those who used to be Hamas fighters, and those who will be Hamas fighters.
Help them get them all with recon and real-time intelligence. No more worries about accidentally offing civilians. PLM!
