What should be done if there's a danger to the suspect's life after swallowing evidence?

If there is a danger to the suspect's life after swallowing evidence, performing a stomach pump, also known as gastric lavage, may be necessary to prevent potential harm. This medical procedure involves inserting a tube through the nose or mouth into the stomach to remove the contents, which can be crucial if toxic substances are ingested. The priority in such scenarios is to ensure the safety and health of the individual, given that ingesting certain items can lead to serious health complications or even be life-threatening.

Other actions, while they may play a role in the situation, do not directly address the immediate health risk posed by the ingestion of evidence. Calling for backup is important for overall support and safety from a law enforcement perspective but does not mitigate the immediate medical danger. Allowing the body to expel the evidence naturally could pose significant risks, as the swallowed items may cause harm during digestion. Accusing the suspect of obstructing justice does not contribute to their well-being and does not address the life-threatening situation at hand. Hence, performing a stomach pump is the appropriate course of action when there’s a danger to the suspect’s life.
