If a carrier is arrested, what is a likely cause of the violation?

The likely cause of violation that aligns with the context of the question is related to the act of tossing a bundle of newspapers to another carrier. This action can be considered a safety concern and a violation of operational protocols. Train operators and carriers are trained to adhere to strict handling procedures to ensure the safe and timely delivery of packages. Tossing items can lead to accidents or damage to the contents, as well as potentially create hazards on platforms or train carriages.

In contrast, errors in handling bundles may result in operational issues but do not directly imply a violation serious enough to warrant arrest. Being unable to show identification, while potentially problematic, usually results in a minor infraction rather than criminal charges. Disobeying a train schedule may have operational consequences but is typically addressed through disciplinary measures rather than arrest. Thus, the act of tossing a bundle represents a more severe operational violation in this context.
