Factual error: The movie is set around 1995. But the SWAT team in the movie is wearing gear from the 2000s. (MICH-2000 helmet, modular tactical vest, M4 variant with picatinny rails and scope). Plus, in a scene when the guys are shopping for a taser (gun shop scene), some of the rifles on display are from 2000s era. AR-15 variants with variant stock, foregrip and picatinny rail. Those style of weapon system were unheard of in early 90s. Even Special Forces just adopted it by the late 90s.
Factual error: While cutting out bloody bits of carpet after the couple is murdered, there is a GameCube controller on the floor by what appears to be a table leg. If the events occurred 1995-1996 as the movie states in captions, then the controller went back in time to be there. The GameCube wasn't available until 2001.
Factual error: When the SWAT teams come to arrest all the criminals, they are shown having the EOTech holographic weapon sight on their rifles. The story happens in 1995 and EOTech introduced the first holographic sight in 1998.
Continuity mistake: When Daniel is lifting at home and Johnny Wu is on TV you can see a red and white MET-Rx protein container with silver dolphins on it right beside the TV. The camera switches angles and it's gone, then switches back and it's there, then it's gone again.
Visible crew/equipment: When they are going to the hospital to find Kershaw, in the outer scene on the right side a camera crane is visible. (01:00:20)
Factual error: In the Schlotzky's restaurant in the background, the fountain drink stall has the new Pepsi logo on it, and also the cash registers are LCD-touch screen devices, with modern pricing displayed. All wrong for 1995. (00:30:45)
Continuity mistake: In the scene where The Rock is escaping from the police and jumped into the water, he is being shot at by the policemen. In the camera shot that shows the bullet piercing his foot, the label on the shoe shows it's the left foot that was shot, but when he gets out of the water and is limping, it suddenly shows that his right foot was hit.Vinotemia
