I was assaulted last week by an acquaintance, didn't press charges for a host of reasons. You're usually asked on the spot if you want to or not and there are enough difficult dynamics at play which could lead someone to, say, not press charges against a superior at work or among the same social circle. As I understand it you can always follow up on your case if you decide you do want to press charges, but the point stands.The logic makes it seem like you might've never been in that situation. Whether you have or not, it's not as simple as it seems.
