I agree. An arrest on its own, even without a conviction or even any charges being laid, can have an enormous negative effect on one's life. Another example is that having been ever arrested, even if not charged or convicted, can bar you from entering the US without going through an expensive, difficult, discretionary process to get a waiver, that then needs to be periodically redone. And it follows you for the rest of your life, it does not expire for example 30 or 50 years after the arrest.
