I'm thinking of hacking into a private security system in order to take personal information.
Why do you need access to information like that?
Why not? I am curious.
That's against the law and you will end up in jail if you keep doing that. That is their personal information and their money they worked hard to get.
I'm making sure people won't get hurt in the long run.
I am not sure how you think that you are protecting people, when you are literally hacking them to look at their private information. You should stop before the law eventually catches up to you.
