Plenty of people don’t report sexual assaults, for whatever reason. Failing to report the incident does not mean they are stupid. Who are you to judge? Regardless, there is absolutely nothing to suggest that the people who are making public statements are the ones who were assaulted, so your assertion that the alleged victims are making unfounded accusations and then complaining when nothing is done is similarly unfounded.
Finally, you have absolutely zero clue of what actions have or have not been taken. Passing judgment on 18-22 year old kids and calling them stupid for not handling the incident the way you want them to is what is stupid. These things generally take more than a couple of days to sort themselves out. As a supposed former prosecutor, you should know better than that.
I mean failing to report a sexual assault is one thing but to fail to report it to the authorities and then put it on social media is another thing
