5. Discussion Schroeder52 found that most weapons trafficking cases from the US to other countries involved transport by car. This finding might be the result of stronger border controls at points where cars cross, especially between the US and Mexico. In addition, the concealment methods employed by arms transporters using cars were quite simple. It is therefore not surprising that traffickers using cars were being caught by customs or law enforcement officials.
