Final answer:
If the police have an arrest warrant for an individual in his own home, but find out he is at a friend's house, they can either wait for him to return home or arrest him at the friend's house under certain circumstances.
Step-by-step explanation:
If the police have an arrest warrant for an individual and they go to his home only to find out that he is at a friend's house, they would typically have two options:
- They could wait for the individual to return to his own home and then execute the arrest warrant.
- If there are exigent circumstances or if the individual is suspected of committing a felony, the police may be able to arrest him at the friend's house without a warrant.
It is important to note that the specific laws and procedures regarding arrest warrants can vary depending on the jurisdiction.
