When Spencer Hamilton is arguing with 4 of the may-be-suspects who killed his brother, Ryan Bartell says Spencer's brother was in a boat. Spencer then gets very angry and says his brother would never get on a boat because he suffers from "hydrophobia", which he thinks is fear of water. It is actually Rabies! Fear of water is "Aquaphobia".
Anyone who's worn a military or police uniform knows the flag's canton faces forward. On one's right arm, that puts the canton in the upper right; but Conrad's right arm has it in the upper left instead.
When Ben arrives on the plane he doesn't carry anything with him but when he arrive at the courthouse, he has his briefcase with him.
Hydrophobia is an irrational fear of water, which is a symptom of rabies, not the disease itself.
While examining Ryan Bartel's home, Ben notices that there is dust on the furnishings, and runs a finger across some of them. He and Conrad should have been wearing latex gloves as a legal precaution, to not disturb any incriminating finger prints, blood, hair, saliva, etc. Even if his home was not the scene of the crime, there may have been evidence in the home of the victim.
