I just like making stuff that seems impossible. Is there anything wrong with that?
What is it exactly? It is an Iron man suit.
What are the practical uses for it? It is used for crime. It can also be used for medical emergency and scientific advancement.
How does it stop crime? It uses data like criminal records, backgrounds and other things like that to predict crime.
Who will use it? I don't know. A general maybe?
