Officer Manzon goes to stand at the bar, there's an extra in a green dress on her left. In the next shot, the extra is suddenly standing on her right.
It is not possible to electrocute a person by dumping her into a metal barrel filled with formaldehyde and clamping two mains leads to the rim. Electricity takes the path of least resistance, which in this case runs directly from one clamp to the other through the metal of the barrel. The formalin solution itself is a much worse conductor of electricity than even tap water, whose conductivity is already fairly low.
When Dexter comes to his home where Lumen is staying, he shows her the pictures of Cole Harmon on his phone, the phone's model is listed as C0 but actually the phone that Dexter is using is Nokia N8. (at around 24:30 min)
Lumen deals five heavy blows to Cole's head with her flashlight and he still keeps moving. In reality, that would render any man unconscious and most likely, dead.
The blows were not actually seen to be hitting his head. Rather, most landed on his shoulders. Even if he were dead, nerve twitches still happen.

During the club scene, one of the Fuentes brothers calls Jasmina "a chingada," a Mexican Spanish curse that is wholly out of place in Miami Spanish, which is strongly Cuban in origin.
The logical thing for Dexter and Lumen to do, seeing that she has been his live-in accomplice for a month, would have been to set up some form of surveillance at the body dump site, like wildlife cameras.
