Which of the following is a concern in law enforcement investigations involving explosives?

In investigations involving explosives, the elimination of electronic interference is a significant concern due to the potential for triggering devices remotely. Many modern explosives can be set off by electronic signals, which can come from various sources, including radios, cell phones, and other electronic devices nearby. This necessitates precautions during investigations to ensure that any response or action taken by law enforcement does not inadvertently activate explosive devices, thereby ensuring the safety of both the officers involved and the public.

While other factors like weather conditions, public perception of police, and budget constraints may also play a role in law enforcement investigations, they do not directly impact the immediate safety and technical execution of handling explosive materials. Thus, the focus on eliminating electronic interference is paramount in these high-stakes situations to prevent accidental detonations and ensure a secure investigation environment.
