The mission of \"chasing the Ghost\" Mumbai (Hitman 2)

The question is:
In the mission chasing the Ghost in Mumbai, after 2 prehoda, performing more than half of all achievements, the sniper rifle so in the cache and has not appeared. Although it involves a few different achievements in the game (to pass all from the observation tower, for example).
Completing certain achievements, gives in addition to points and even some kind of bun, but the sniper in the awards I never found.
In General, where?

Second question: the Task of getting rid of a hidden character, when we need to monitor a bunch of people and identify the victim.
Got a job with the hairdresser. (did everything)
Stood waiting at a Barber shop, he perebral a lot of people, this asshole just went next and did not respond. In General 2 hours spent in the shuffle and in the end he just slaughtered in the alley.
Who ran achivku may have done something wrong?
Also this game looks the following way: Shave the victim to blue, and to finish don't forget to

And some more: In a skyscraper, there are 2 in a bundle: save kakovata dude are going to drop from the roof (based on the pics) - also didn't find anything similar.

And finally: also this game with the train, I couldn't understand. Train for hangar sometimes rides, but what I do not understand.

Thank you, share cheats,
