Charge it up and then drop his phone and items in an spot near an elementary school playground early in the morning before the kids arrive and then call in a suspicious person to the police the next afternoon during recess. Cops show up and find his items. Cops don't take kindly to pedos jerking off to the neighborhood kids. Remember that cameras are everywhere so hide your identity.

Cops won't do shit but file a report. Just fyi, if you decide to take matters into your own hands, you're already 75% caught by talking about it here, and If you've talked to anyone in person about it you'll likely be snitched on. Tread carefully.

Does he have a parole officer? They'd probably like to know your car was broken into and they left their phone.

Blackmail him for the cash plus damage interets or else you start going neighbor to neighbor singing tales of his criminal exploits with proof of registry. Set up signs near street lamps. It's not illegal (the telling and signs part, of course).

Is he a nigger?

Observe and report when something inappropriate happens; the scummier option is blackmail and reporting when you made him bleed out financially

Where is the option to just end it?

Im torn between 1 and 2.

But 1 could end up with you being a felon for assault.
