<human>: I was sexually assaulted (groped) by a teacher 11 years ago in Wisconsin. I was 13 years old, naive, scared and never reported it. Now I feel extremely guilty knowing this creep is still a teacher and could have a decade's worth of victims just like me. I read up on my state's statute of limitations and I think I am still within the time frame to be able to do something about it. 

 I just need to know if I should be going straight to the police or if I should try and find a lawyer first. I am not interested in receiving any type of settlement whatsoever,  I just want there to be a record of his actions. I was assaulted on a class retreat and I witnessed him possibly assaulting another girl the day after I was attacked. I never confronted her or asked about it. I am hoping to contact her now, but we are complete strangers and I was hoping for some advice on how to go about that. 

I know it was incredibly dumb for me to not have reported anything when I was younger but I was honestly extremely confused and had convinced myself that it was an accident for YEARS. Any advice regarding taking action now would be appreciated!

Can you give me the gist of the text in a nutshell?
<bot>: Groped by teacher 11 years ago when I was 13. Should I go straight to police or lawyer up? How should I go about contacting other possible victims?
