My question is about the scene where that robot releases a centipede into Padmé's room. Why didn't the thing simply shoot her through the window or explode outside or inside the room? Dying from a blaster shot or an explosion is going to be no different than dying from an animal that would be impossible to get attacked by in her location. When the autopsy is being conducted and they discover she was poisoned by that thing. It's going to be easy to tell the thing was placed in a location with her in it since the thing can't fly and the city is miles above the ground. Also why didn't Fett simply snipe her since he was located around her room? He was on a building that is over looking her room so he could have fired a powerful rocket at it.

I looked them up and according to the Star Wars wiki they are difficult to trace, but it still doesn't mean you can't trace the death to them. In the long run it still would have made more sense just to shoot her or blow her up. Her ship already exploded so people already know there's an attempt on her life. Trying to kill her stealthy is just a waste of time and pointless due to that. If she did die from those things chances are in the autopsy they would detect it since they would be looking hard to see what she died from due to the ship explosion attempt.
