Wish it was that easy. What we have to remember is Sadr
City is a huge area in the city of Baghdad. What you
suggest simply would not be possible because it would
require litterly thousands of snipers to be hanging out
on equal amounts of houses and buildings, etc..
Just picture Sadr City as a area as big as Broklyn NY.,
filled with row after row of homes. Plus please remember,
we no longer in most cases control over what battle is fought where unless our guys are fired upon. It is up to the IIG (Iraqi Interim Government) to decide when our forces are required to do a "mop up". Sadr City houses
probably over a half million people. We just can't go in
and kill people. How do you tell 3PM in the morning, for
instance, what a person is carrying? You are aware I am sure that all Iraqi's are permitted to carry a AK47 rifle for self protection. So as you can see, it is not so easy
to do what you wonder about. Hope this answers your question.
For anyone interest, you may want to read and article I post the other day titled:
Something you won't see in the MSM author: Marine_Uncle
It will give a nice picture of current events 12 miles south of Baghdad. It fits into what the Major shares here.
