"Thermite is pretty cheap to make. Use it to melt/destroy his car. Do that, and he likely loses his job as he can’t get to work, unless he pays to replace it. In which case, do it again." source: https://raddle.me/f/Illegalism/107125/best-way-to-fuck-someone-over

First question is - how do you know he is a pedophile? has there been a trial? how did he get off? publicity itself is usually enough to destroy one's career and family.

As for the car - steal some license plates to use briefly (put them on and change them just before and after when you know you aren't being followed) or drive near by with a bike (making sure there are no cameras where you park) then bike to where his car is parked and back. His gas tank is probably locked - be prepared to pry it open.

Just park the car away from houses and walk for like 5 minutes, safest way

I have no experience at all with any of this, but is it close enough to walk without being watched?

Set it on fire. More spectacular...

As OP said, there are cameras.

They'd definitely track the car, you'd have to cover the plates at least

Is it Hakim Bey's car?

Just walk or ride a bike like many others said. Or drive and park down the road.

Also if you get sparkplugs, there's a little ceramic bit inside of them that will break any car window you throw it at.
