One time in high school I swatted this kid by calling the cops and telling them he was holding someone hostage.
Did he do something or did you just feel like calling the cops?
Nah, he looked poor, so I thought it would be funny if he was arrested
Not liking someone is fine but what you did was extremely wrong and dangerous. You used a legal system to scare the heck out of this guy when he could have been shot and killed if something went wrong. You're lucky it never got back to you or you would be the one getting arrested.
That's what I did to him for like five minutes, then called my buddy to get him out.
Calling the cops on someone just as a joke is extremely wrong. You could get the kid into huge trouble or even get yourself into big trouble. In addition to this, you are wasting the time of law enforcement who most likely have more important jobs they could be doing.
