Dade County did not change its name to Miami-Dade County until November 13, 1997, 2 years after the movie setting, but police cars in the movie have the longer name.
When the characters are in the gun shop, rifles can be seen on the wall with MAGPUL stocks. Such stocks weren't released until the mid-2000s, and would not have existed in 1995.
In the Bahamas scene, where Kershaw sees Lugo fleeing on foot, he attempts to drive a car from the passenger seat. While the car is crashing through the small business stands, a stunt driver can be clearly seen driving, in multiple scenes which ends after the car crashes into the wall, giving us a clearer shot of the stunt driver.

Paul Doyle: Why'd you make me do that to you, Victor? I have responsibilities! Jesus Christ himself has blessed me with many gifts! One of them is knocking someone the fuck out!
Lugo led the police to where they were seemingly. Bottom of this page.
