<human>: Condense the text into a few key points

As with so many TIFUs, it wasn't today, but when I was a young,  innocent,  stupid middle schooler. My father had just returned from a business trip and brought me something that was shortly going to catch on in a big way: a laser pointer! Why he thought a 13-year old needed a laser pointer is unclear,  he probably just assumed I was going to play with the cat with it. And I did! But then I thought to myself,  if I can get a cat to chase this, how will people react? I waited until dusk and then decided to find out.  I lived in a townhouse,  and there was a fair amount of foot traffic past our house. Most people seemed confused, and my favorite was when I got an old man to walk in circles chasing the little red dot. It was hilarious for me, and dusk soon turned to dark. My neighbor across the street,  the wife of a police officer, came home, her arms full of groceries.  I pointed my laser on the door at about eye level.  She stared at it for a while, then quickly went inside. Not much later, her husband, the cop shows up at the door, and he is *pissed*. What I thought was a funny prank was interpreted as the laser sight of a gun. She had spent the time from my prank to the arrival of her husband terrified and hiding in her house, certain she was about to be murdered because of her husband's profession, and he had to leave work to make sure she wasn't. I got a lecture from him and had to promise not to do that any more, but essentially got off scot-free. My parents didn't take away my laser.
<bot>: Middle school me playing with a laser pointer accidentally made a cop's wife think her murder was imminent and made her husband rush home to save her.
