Summarize this article:

The police need to find the bomb, so get its location. Obtain as much detail as possible: building floor room location in room Say, "Can you tell me when it will go off?" The police will need this information also. Write down whatever the caller tells you. Get some details about the bomb, which the police will find useful. Ask the following questions: "What does the bomb look like?" "What's the bomb made out of?" Ask the caller, "Why did you place the bomb here?" If they say they didn't place it, then you can note that information as well. Many bomb threats are called into religious institutions, such as places of worship or community centers. Be prepared for the caller to use derogatory language. Nevertheless, write down exactly what the caller says. "Can you tell me your name?" The caller might give this information, or they might not. It can't hurt to ask. Write down whatever they tell you. They might give you a made-up name, like "Avenger of the Night." The caller might withhold helpful information, or they may talk all over you and not let you ask a question. Continue to ask questions anyway. A good technique is to mirror what the caller has just said and then follow up quickly with a question. For example, you can say, "I definitely hear that you've put a bomb in the school. Can you tell me why?" If the caller refuses to answer, ask again.
Ask where the bomb is placed. Ask when the bomb will go off. Ask what kind of bomb it is. Check why the bomb was placed. Ask their name. Be persistent.
