OK... I give up.
You've obviously amassed a great deal of proof that these allegations are true. No doubt through exhaustive research on your part, (in the other 20% of the time you're at work?), you are now able to provide incontrovertable proof that this guy not only did what was said (probably worse), but also that he'll continue to do so... especially now that enough time has passed (8yrs) that he'll raise less suspicions.
I say we sentence him to 50 years of hard labor, and ban him from football for life.
Somebody, please grab some torches, and gather up the rest of the vigilante mob, so we can go raid his house and make sure justice is done!
