Many cities need help to keep people safe. The city leaders ask the government for help. They want more people to stop crime.
The leaders and the police chiefs have a meeting. They talk about what they need. They agree that working with others is a good idea.
The cities say "yes" to some help from the government. They want federal officers to work with their local police. This will make the police team stronger.
But, the cities say "no" to soldiers in the streets. They do not want an army in their town. It would feel like a takeover, not help.
