sorry won't cut it; just saying sorry isn't enough
A set phrase used to reject a mere apology when real consequences or compensation are expected. Often said in a scolding or cynical tone.
You broke something and all you say is 'sorry'? If sorry were enough, we wouldn't need the police.
If you think apologizing will make everything okay, you're dead wrong. Sorry won't cut it.
A common Japanese saying. Literally 'If it could be settled with an apology, we wouldn't need the police.' The exact origin is uncertain, but it has been used as a proverbial expression for many decades.
