If someone is charged with assault, there can be a myriad of defenses. Not only can we hopefully prove that the assault was not intentional, not serious, or not actually harmful- no injuries occurred- but even if there were some slight injuries, even if there were some words that accompanied the assault that made it seem like it was done in a vengeful maner, there's still a lot of ways assault charges, especially domestic charges can be negotiated in the person's favor.
