Why don't these police ever shoot back?
There is no way to tell if the police shot back or not. These are carefully planned raids by terrorists/insurgents; if they did not outgun and outman the police, they would not bother to attack. The story, as are most of them, is written by Reuters. They are a mouthpiece for anti-Americanism and victory for jihad in Iraq, or anywhere, against America. To accept their version is to accept that all of Iraq is against us, Saddam was an okay guy, etc. Get real. The truth is not rosy, but it is not nearly as bad as Reuters portrays in every one of their blankety-blank stories.
Most of the time they are out gunned and out numbered. What they need to do is over run Al Jezzera and start executing reporters for broadcasting this crap and send a message to them. You support them, you'll die like them.
