if someone who is very bad, smokes weed and cigarettes, drinks a lot of alcohol, fights with people, shows his anger on people, takes other people's money and doesn't pay them back, wants to beat up his own siblings.

This guy has a iPhone and you want to track him, BUT you DON'T know the apple id or the password to go on the Find my iPhone and he didn't do the payment for his sim card (you need pay the sim card in order the data to work). This someone/this guy that I said at the beginning is my very own brother.
I want your opinion on your idea on this. What should you do?
I have no time to answer people who says "what do you think?"
I need help.

You could turn him into the police.

I don't mean to be rude but maybe you should talk to someone else instead of using a homework helping site

my parents called the police on him but the police didn't take any action

I agree!

Then -- face it -- there's nothing you can do.

File a law suite against him... IDK why I said That!

i think you should kick him outside of your house

There is always something that can be done and there is always someone, somewhere who will help. If it was me, the first person I would ask for help is a teacher that I trusted and looked up to. If that teacher is truly caring, he/she will find a way to help you or find someone else who can help. When you stop to think about it, it is really your brother who needs help. He is on a path that will only lead to a very bad end.

Lee is correct!

Go to your school consular and ask for advice.
