Whatsapp — admin rights

Why the admin can not have the option to remove member's post anytime?

Then how can call them as admin without remove rights???

I m software engineer and in my knowledge, an administrator is one who have full permission or full control like add, edit, delete, etc (Crud)

Here the rule in our country says admins are responsible for criminal or harrasing related posts from memebers.

So please add "remove post from everyone" option for admins in group chats and should not be a time depending of 7 minutes.
