Concerts as shown with no barrier between the performers and inmates would not take place at a maximum security prison since that would allow for the performers being taken as hostages.
The uniforms and badges worn by the state prison guards are for Dade County corrections officers, not the Florida Department of Corrections.
Crockett is shown riding a motorcycle without a helmet. Florida had a mandatory helmet law in effect at the time the series was in production and that law wasn't rescinded until the year 2000. So he would have been in violation of the law in.
Vice officers would not respond to the scene of a city police officer being shot; however, Crockett is clearly responding in aid of a fellow office because he was on the spot.
The Florida State Prison is in Raiford on the northern end of the state hundreds of miles from Miami, and Big Pine Key is in the Florida Keys about 100 miles south of Miami, not the 20 miles stated. Additionally, there is one road that goes to the Keys- US 1, not "67" as stated.
After Crockett crashes the black car and takes the Jeep, he drives off in the opposite direction from the people he was chasing.
After the beating Crockett took his face should have been hamburger meat. Instead the the closing scene his face is unmarked.
After the shootout in the street, Crockett commandeers a civilian's vehicle instead of taking the police car. This would put him (and both his and the local police department) in liability if the driver was injured or the vehicle was damaged, as it ended up being.
