When Maria exits her car and passes the first cargo container, she wears her badge. There are several cut shots as she approaches the open container door. Before she enters, her badge has been replaced by a laminate similar to Dexter's. After the shot is fired and Deb enters the container, Dexter positions Maria against the opposite wall. She is wearing her badge again.
In the flashback scene where LaGuerta is talking to Doakes, LaGuerta is wearing a silver shield, however she is a Lieutenant (we see her office door with her name and rank on it in the background) and so she should have a gold shield.
When Hannah is lying in the ER after she seized in the police van she is not restrained and therefore can leave. Normally a prisoner would have been handcuffed to the bed.
She is restrained. At 29:23 the zip tie restraint can be seen that is taking the place of handcuffs. She cannot get up and leave.

When Deb arrives at Dexter's place and turns to shut the door, the slit up the back of the fake cast she's wearing is clearly visible. The make-up or props departments - whichever was responsible - should have put tape over it to disguise it.
