The Superhero in the Alley - S1-E12
Factual error: Booth is supposed to be a (former) Army sniper. Military personnel chosen to be snipers are expert shooters. At the young mans grave, Booth places a sharpshooter badge on the boys casket. Being a sniper, Booth should be an expert and, as such, should have placed an expert badge instead of a sharpshooter. (Rifle and Pistol sharpshooter badges in rank lowest to highest: marksman, sharpshooter, then expert.)
