Lets put it this way. the media is anti- Israeli from the offset, and the fact that because Hamas is firing from civilian locations, civilians are going to, and are, being killed in the response.
Why should they let in the media, when they know that whatever happens, even though they are responding, almost all the reports will be against them, and a question i've asked a few times, without an answer, Hamas was the first to fire, thousands of rockets before Israel had had enough and responded, What would an appropiate response be, to an organisation that won't stop firing their rockets?.
