As a frequent traveller through DME (and SVO 1/2) I have seen the security increase dramatically since the late 90's - and generally the level of diligence is high - although have seen some glaring exceptions - but perhaps I wasn't viewing the entire picture.
However entering the arrivals area is like a zoo (with all the competing taxi mafia) although better than SVO2 is still completely disorganized and chaotic.
Their are all sorts of odd characters wandering around, often seemingly outnumbering the passengers.
DME should have made a complete break from the SVO mentality set.
