Disturbing Thing You Saw

I’m curious because I hear about crazy shit all the time on true crime and dateline.
I hope you stay safe guys. I know it’s ironic coming from a random person on an illegal manga site, but whatever.
Be careful about where you put your name, and pictures or videos of you.
I know most of y’all already know this crap, but it doesn’t hurt to say it again.

should i buy one? a criminal is gonna come to my house sooner or later, but i dont have any evidence against him. i want him to stop but i don't wanna turn him to the police, so i thought of threatening him.
if so, should i wait until after covid or should i buy one asap? where should i hide it (bedroom)?
im being serious.
