Pathankot and the Paris attacks are Apples and oranges
1) Pathankot is a VAST military installation with a 24km perimeter wall with hundreds of buildings/storage areas that EACH had to be cleared by the NSG
2) The actual combat operation of the NSG lasted only around 10 hours (after which all terrorists were dead), the four day timeline blindly repeated by the media is how long it took the NSG to sweep every single nook and crany of the vast installation in what they refer to as their "render safe" drill. This is standard NSG procedure wherein the force commander (the supreme authority on the ground in charge of all ops once the NSG offcially steps in and whom not even the PM of India can overrule) will not declare the operation offcially over until the drill is complete and he is 100% confident that not even a single live round is unaccounted for. These drills often take far longer than the combat ops but the media spin the entire durtion as "combat ops".
3) Conversly, in other countries the counter terror forces deploy, conduct combat ops and retreat leaving local/federal police forces to sweep, take care of muitions etc whilst the NSG take care of the entire process from "boots on the ground to render safe" meaning when the NSG pull out the site is 100% safe for any other agency to come in.
4)It is this difference, that the media just do not understand, that often leads to these highly inaccurate timelines being attributed to NSG ops. If the NSG did not have the "render safe" drill as part of their SOP they would have the same "swiftness" as any other unit.
