Henry (played by Spano himself) has his bowtie untied around 13:52 and in the next scene it is tied perfectly at 14:22.

Ray sounds off at his award banquet about not being recognised for who he is, just a token hispanic thing. Then Washington shoots a the wrong guy at a hold up while staking out a massage parlor with Belker. He told him to drop it. This is why you need to learn the language of the land. If that guy had understood and not turned the gun on Washington, he would have had a chance to drop the shotgun instead of getting killed. I found out once that if the police are aiming at you telling you to freeze, you better fall down on the ground and wait for them to sort it out. I can't imagine what went through this guy's head, though, since it was his store, he assumed the police would know he wasn't a robber. The get away driver ran off and left the guy who got shot. WHY does anyone think a shootout with the police is going to be a good idea? They practice constantly and have to qualify at the firing range at least every month. What are the odds he is going to miss you when you shoot at him? None.
