The standard issue pistol of the FBI is the 40 caliber Glock, not the 9 millimeter Glock as stated by Detective Green.
There are several different cartridges that use the same bullet as the .38 ACP and more that are extremely close to the same size, including the 9mm, It is the cartridge case (where the powder charge is located) that differentiate the various cartridges, not the bullet (which is the projectile) itself.
When Briscoe arrests Carolyn Tyler, he calls her "Caroline Teller".
When Ms. Carmichael is verifying Tom Berringer's alibi, she states that he was working a 4X8, which gave him his alibi. But, the correct term is and 8X4. The way it was spoken, would have given him a four hour work day.
