The Importance of Defensive Coding

You can never be 100% sure that someone's not going to change your abstraction. So this is another good argument against like creating a bunch of those abstracts as I like to think about. If you have a function that expects an admin user to be passed in and that function doesn't check that it's an admin in some way, someone A, someone could delete the if admin, like block. And now suddenly you're passing in users that shouldn't have admin access to a function that only allows users with admin access or something like that.
