Which of the following is NOT an example of common practices for law enforcement in regards to animals?

The choice relating to allowing the ownership of poisonous or dangerous animals is correct because standard law enforcement practices typically involve regulations and restrictions regarding the ownership and keeping of such animals. This is often done to ensure public safety and animal welfare, as dangerous animals can pose significant risks to people and other animals.

In contrast, the other practices listed—regulating animal fighting, prohibiting animal neglect, and investigating reports of animal cruelty—represent proactive measures taken by law enforcement to protect animals and promote humane treatment. Each of these practices reflects a commitment to enforcing animal welfare laws and ensuring that animals are not subjected to harm or exploitation. Thus, the presence of these practices illustrates a legal framework aimed at safeguarding animals rather than allowing ownership of potentially dangerous species without restrictions.
