I'm going to cause troubles for my boss even though it's technically his fault.
Why do you want him to get in trouble?
To be let off the hook.
While it is normal not want to be punished for what you didn't do, accusing your boss could get you in more serious trouble. If they take his side, then you will be fired.
The world is full of stupid people, who gets fired for stupid reasons all the time.
Are you saying it's worth risking getting fired? It's almost certainly not.
