In the scenes when Amato's house is under surveillance, it would be impossible (with early 80s technology) to use a 200X telescope clearly while on a bobbing sailboat, but as shown, the telescope view is rock solid, while every other view from the sailboat is shown bobbing with the water.

In the beginning Tubbs is ranting about being shot at by a .30 caliber M-60 machine gun, and although he is technically wrong as it uses a 7.62x51mm cartridge, 7.62mm is exactly .30 caliber. Despite being called a 7.62x51mm cartridge, the actual bullet is 7.82mm wide, or .308 caliber, and is often called .308 Winchester or even .308 NATO. With all these different designations for the same cartridge, it isn't a surprise that Tubbs is not 100% accurate after being shot at by many of these bullets.
A character pulls the cocking handle of his MP5 submachine gun. The MP5's cocking handle is only used when reloading, where it is pulled back to a catch before the new magazine is inserted, and then it is released from the catch. The cocking handle is never simply pulled back and then released.
In the scene at the airport, Detective Switek (Michael Talbott) nearly knocks over a little kid, obviously, an extra, who passes by him. Talbott, to his credit, stays in character, but you can see him looking back as he moves to make sure the kid was OK.
