In season 5 of Star Wars: The Clone Wars, when the Jedi Temple was bombed (which put the Jedi Order in suspect only to damage their reputation) I thought Palpatine was behind this.
All militaristic setup to lure Ahsoka in the trap made my belief more powerful.
But, in the season finale, it was shown that another Jedi was behind this and the trap against Ahsoka didn't look official after that. It looked possible for a Jedi to setup such things (putting key card in front of Ahsoka, killing clones with Ahsoka's lightsaber etc).
But, I still suspect about Palpatine's involvement. Is there a solid clue to say Palpatine was involved in this from any level?
