When Fin is recording the first two victims with Alexander, the setting on his phone is clearly switched to the still pictures option, not the video option.
The episode takes place in October but when Stabler and Benson search Camille's apartment and find a picture from summer camp. They talk to the owner of the camp. There are kids at the camp. Why would there be summer camp in October? The kids should be in school.
ADA Hardwicke says that they don't have enough to arrest Camille and hold her because the victims didn't identify her and they don't want to press charges on the breaking & entering and assault, plus the GPS on her cell phone puts her across town at the times of the first two attacks. However they found her in possession of Ketamine, which is a Schedule III controlled substance, so they could have at least arrested her for unlawful possession of a controlled substance.
Alexander Gamon was a counselor at the summer camp where he met Camille Walters. The owner of the camp said Alexander was a counselor and Bill Dixon was a lifeguard but in court, Alexander said he was a lifeguard.
