Okay, so imagine there are two groups of people. One group makes weapons, like guns and bombs, and the other group wants to buy those weapons. But, buying weapons is not always legal or safe, because sometimes bad people use them to hurt others.
There are some people in the middle who connect the group that makes weapons with the group that wants to buy them. These people are called brokers. It's like they are in the middle of a big puzzle, connecting the pieces together.
Now, the brokers of the death arms case were a specific group of people who were caught selling weapons to bad guys who were using them to hurt innocent people. This is not okay! It's like giving a dangerous toy to someone who will use it to hurt people.
When the police found out about what the brokers were doing, they arrested them and put them in jail. This is because it's against the law to sell weapons to bad people who want to harm others.
It's important for everyone to remember to always be kind and to not hurt others. And, people who do bad things will always get caught and punished.
