Continuity mistake: When Roy and John walk into Edna Self's house, in her closeups she's wearing a light beige floral robe, but in the shots facing the guys we can see that it's a dark solid color robe that's on the chair. Notice how odd it is that the three are not in any shots together - Edna's not in any shots facing John and Roy, and they're not in any shots facing her.

Continuity mistake: When Johnny and Roy get back to the station and talk to Paula in the rec room, in the wide shot Johnny has his hands on his hips and then subtly moves his elbow behind Roy, but it cuts to a close-up and his elbow is still blocking Roy.

Continuity mistake: When Richard jumps out of Rampart's 6th floor window, the bottom of his feet are very filthy (impressive for someone in bed in a catatonic state), but when he wakes up while lying on the ledge and Johnny tries to control him, Richard's feet are now pretty clean.

Continuity mistake: When Bo goes to Richard's room for the first time, in the view from inside the patient's room, as Bo pushes open the door we can see the hallway behind him, and there's a perpendicular wall beside the door. This wall does not exist when he visits Richard the second time, because there's a hallway leading to the elevator outside of Richard's door.
The Promise - S3-E11
Continuity mistake: When Bo Jensen goes to Richard's room for the second time, as he pushes open the door we can see there's a wall perpendicular to the door, but when Bo is in the room there's a wide widow covered with curtains where that wall was. The window with curtains can also be seen in the exterior shots, when Richard jumps out the hallway window.

Continuity mistake: When Roy and Johnny try to subdue the out-of-control patient on Rampart's ledge, after Brackett tells them that he'll go to x-ray right away, Roy's helmet is off, but in the overhead shot it's on his head, then in the next shot Roy puts it on his head.

Continuity mistake: When Station 51 is dispatched to the people trapped in the house, Johnny and Roy clear away all the tumbleweeds from the front door, but in the next shot facing the door there is another huge tumbleweed in front of it.

Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
