Continuity mistake: During the stakeout of the apartment building, in the exterior shots of the Clyde Motorcycles shop, Danny is peeking out through a ripped paper opening within the letter "D" in Clyde. However, in the interior shots the black tape letters of the word Clyde differs. The paper is ripped between the two letters "D" and "E" and that space within the "D" is blocked with molding, making what is in the exterior shots quite impossible. (00:15:40)
Continuity mistake: During the takedown at the apartment Danny is entering the building wearing hoodie and the shield around his neck, going upstairs, the next shot he is in shirt tie and vest at the staging area, then he is back in the apartment in the doorway in his hoodie, then he is in the street in vest and tie. (00:20:48 - 00:22:21)
Suggested correction: Danny is not one of the 4 men who follow Maria Baez inside and up the stairs (at 00:20:40). They are John Knight and his 3 men, all plainclothes with their shields hanging from necks. Earlier, right before Baez and the 4 men head out to the apartment, John Knight is standing near his 3 men inside the Clyde motorcycle shop (at 00:18:46 for example). Rewatch please.
