Which of the following can be a result of a crime committed for terrorism purposes?

The result of a crime committed for terrorism purposes can indeed include the lengthening of the statutory maximum for the underlying crime. This is often a legislative response to the severity and threat posed by terrorism-related offenses. Lawmakers may choose to enact stricter laws and increase penalties to deter future acts of terrorism, reflecting society's heightened concern about security and the profound impact these crimes can have.

In such cases, the legal system often recognizes that acts of terrorism are not just crimes against individuals but attacks on the very fabric of society, leading to harsher sentences that can extend beyond normal statutory limits for similar crimes. This response aims to provide a strong deterrent effect and convey the seriousness of terrorism-related offenses to potential offenders.

Other options such as decreased local law enforcement presence, increased community cohesion, and reduction in legislative oversight do not align with typical outcomes following terrorism-related crimes, which generally lead to increased law enforcement presence, potential community division due to fear, and greater legislative scrutiny and action.
