Suggestion for Apple but don't know an email address to send it too

I have a suggestion for Apple about their find my iPhone feature. What I've noticed is if you have find my iPhone turned on, you can simply go to settings>iCloud>find my iPhone then simply turn it off without needing any kind of Apple ID or password what so ever. This seems rediculess to me because lets be honest, any theith whos gonna steel an iPhone or an iPad or whatever is gonna be smart enough to know that. So I think you can tell what my suggestion is, you should have to enter either the password you use to unlock your device if you have one, or have to enter your Apple ID and password. For added security they could also make the find my iPhone settings hidden maybey? Let me know what people think of this, or if anyone can give me an email address where I could send this to apple. I know there is accessibility@apple.com but it's not really an accessibility issue. Like I said just let me know what you think in the comments. Thanks.
