On Booth's computer it describes Paula Ashwaldt at 5'11" and 185 lbs, but the next scene shows Paula portrayed by Marisa Ramirez who is 5'6" and too slender to be 185 lbs.
On Paula Ashwaldt's dossier, it mentions her date of birth as 08/30/1974, and her high school graduation is listed as 1998. That means she would have been almost 24 years old when she graduated from high school.
At the beginning of Act I Hodges announces that the victim was a counterfeiter. What makes this fact rather odd is that when the team were examining the body, there were numerous bills lying around the body, and one could see they were $100 bills, but the portrait on them wasn't the usual one of Benjamin Franklin; in fact it wasn't clear whose portrait was on the bills, making it look like the victim was a really bad counterfeiter. No one would have accepted those bills.
Broadsky bought some specialized ammunition from Benny Winkler, but using the ammunition would require an equally unique gun: where did he get the gun? Making an accurate gun barrel requires extreme precision and isn't something that could be done by a typical machine shop.
Benny Winkler says that Broadsky described his target as "a rectangular room ... with marble paneling and a marble floor, and a ceiling 12 feet high made of copper". Using these details, Angela and Caroline were able to identify Broadsky's target, but there was no reason for Broadsky to give these details to Winkler. The materials used for the floor and ceiling couldn't possibly be significant for Broadsky's purposes.
Angela describes the bullets as being 20mm and 25mm in diameter. Those size bullets would be fired from a machine gun or cannon, not a sniper's rifle. For comparison, some large caliber sniper's rifles fire .50 caliber rounds - about 12.7mm in diameter.
Under questioning by Booth and Caroline Julian, Benny Winkler said that he "can't be charged for simply selling ammunition." This is false on at least two counts: under Title 18, US Code section 923, "No person shall engage in the business of ... manufacturing ammunition" without a license. Additionally, explosives (including exploding bullets and grenades) are regulated as "destructive devices" under the US Gun Control Act of 1968.
On Booth's computer, it states that Paula Ashwaldt was born on August 30, 1974, and that she graduated high school in 1998. She would have been 23, turning 24 that August. For the both of the graduation dates to be correct (High School 1998; College 2002), she would have to have been born in 1980 or 1981.
