More context needed to enable accurate rendition 00:47 Aug 3, 2011
Greetings.
More context is CLEARLY needed to enable accurate and suitable Arabic rendition. That phase sounds much like professional [police SWAT -- as Hassan Lotfy mentions -- or CT] slang uttered in some dialog.
That expression of "We have intel on the back door" when uttered in US "Police English", usually equates = we have information about the features of the back door [i.e. dimensions and strength of the door and its frame], any measures of surveillance or defense, plus routes of approach and assault so that the SWAT operators can breach the door and enter a building rapidly to dominate the situation.
Above comments based on my many years in a military unit with similar missions and concerns about "doors, locks and windows" as priority factors when planning and conducting such special operations.
Hope this helps. Khair, in shaa' Allah.
