Answer:
The group is committing a crime and the police are expected to arrest them.
Explanation:
The police can arrest people who are trying to manipulate other citizens' votes. This is because it is prohibited by law to give political campaign, to try to induce, manipulate, or coerce anyone to vote for any candidate near the polling places, much less in the crack of them.
In this case, the group of people mentioned in the question above are committing an electoral crime and should be punished for this misconduct.
