I put on my Assassin attire and strap my hidden blade to my hand, i take out my sword and put my dagger on my belt. All the guards were at a public execution, so they wouldn't be there, and it was an Assassin's execution so the king and all the others were watching, there would no doubt be a fight between the assassins and templars. But i focus myself on the matter at hand. I walk out of my door with my hood over my face, my hidden blade has "fresh" blood to make it seem like i had killed someone in the last hour or so.
