I have a question for everyone: How do I get past the guards by the book depository? I am at the point where I went through the sewer and now I cannot get past these guards. I've tried all the psy abilities and keep getting escorted out of the area

Check the hints thread for this kinda thing, but heres your answer anyway

You need the sniper rifle which Boyd will give you once you have gotten past the graveyard part

Hmmm, I'm stuck in the milkman level as well... Can't find a way to get past the phone-line worker and the two dudes with the scissors in the garden. Do I need to find some objects, and where can I find them?

I was stuck where you are for quite a while, until it dawned on me that I could jump to another stretch of sidewalk and continue exploring.

And yes, you need a special object to get past each type of g-man. I don't remember exactly where the different objects are. Some are in car trunks, others are in houses, a few are in special buildings requiring some puzzle-solving to get at.

Hmmm, I tried that multiple times, but somehow Raz falls down, even though he's supposed to land on the ground... I'll try again, just to be sure, though.

Just to be clear; I already passed the road workers, and jumped to another section; the one with the telephone pole worker and the gardeners. I doubt I'll be able to jump to another part from there, but as I said I'll try again...

I believe that even without other items, you should be able to find the post office, the grave yard, and the hedged-in courtyard, just by jumping from sidewalk to sidewalk. IIRC the clippers are optional and not necessary to move forward. You do (eventually) need the plunger, lily, gun, and phone.

Edit: I think the easiest spot to jump from is where two cul-de-sacs are at just about 90 degrees to each other, shortly after the road crew bit. It should stand out as being an unusually short gap.
