u dont need rocks , what u do is go around to where the doors are and get jackie to climb up the wall by running and jumping up the wall ( repeat this move 2 or 3 times for it to work) then go to the second lot of windows and find the broken window then get the key from the gaurd and your preetymuch set for the museum level

once you start the mision you should see a open gate at the right of the museum. then you should see a door ,you cant get in so you should jump from side to side on the two walls on each side of you.

wen youre at the mueseum the door is locked so you got to the right and turn left and you
will see a gate and a door go to one of the walls and jump left righ until you re on the
roof and if you look around youlle see a smashed window and just go in
