I'm not convinced that this "car mechanic" was a car mechanic. How did he know the name of an Israeli Colonel? Iraq has been caught before using officials of the central government as the subjects of "man-on-the-street" interviews, a practice which thus far the Western media has been all too happy to accomodate.
Further, even if this was a real "man-on-the-street," many Iraqis believe as many as 1 in 7 adults are paid informants for Saddam. Therefore, if you talk to them on the street they will say only what they would say to Saddam himself. I am not at all convinced the average Iraqi is happy about this.
Now, as for the Palestinians...
