so harmsworth got arrested for talking to some police officer online, while u went and traumatized a bus full of women and children, and we're supposed to side with u? whose gonna be having more nightmares tonight? the sick, twisted police officer pretending to be a 13 year old girl, or all the innocent people on that bus, whose lives u ruined? you're a sad excuse for a human.
Wait for him to get off the bus, follow him to where nobody is around and hit him all you want.
You remind me of the video of a London train where some woman starts racially abusing everybody around her with a 3 year old kid it seems sat on her lap looking lost as balls.
You're a tool OP, now provide pictures of your sister.
"Every man's heart one day beats its final beat, his lungs breath their final breath. And if what that man did in his life, makes the blood pulse through the body of others, and makes them believe deeper in something larger than life, then his essence, his spirit, will be immortalised by the storytellers, by the loyalty, by the memory, of those who honour him and make whatever the man did live forever."
OP, just because you're mad that this fellow cheated on your sister with a (so he thought) 13 year old girl (say's a lot about your sister), that is no reason to make a scene and upset the kids on a bus. You could have potentially given an old lady a heart attack. They could have developed anxiety problems from your actions. If you wanted to do something about it, you should have waited for the prick to get off the bus and uppercut his face. Hell the police would've probably given you a slap on the wrist. I'm sure they don't mind seeing douches like that get their comeuppances.
