Systematic destruction - Swedish journalists in Gaza

Aftonbladet journalist Peter Kadhammar comments on the situation on the ground in Gaza;

"A surgical attack. Surgical destruction. ... The precise cuts shows that there was a clear plan behind the attacks, but we haven't gotten answers to our queries. In what way did the Department of Finance threaten Israel's security? The Cenus Office? The Department of Agriculture? The Legislative Council?

In the end it all boils down to one word. Why?"
