<human>: So, like most fuck ups, this didn't happen today. This happened around 7 or 8 years ago when I was in the 6th grade. Keep in mind I was 12 years old at the time. A little backstory first.

I attended a private school that had middle school and high school attendance. Every few years, the city police department puts together a drunk driving presentation for all of the high schools around the city, warning kids about the dangers of it. They take a smashed up car, and some fake "dead bodies", and create the scene of a car crash on the school campus. It's actually very cool. Now, to the fuck up.

They had the entire high school gathered in the gym, as they the police were going through a slide show presentation. The entire gym was blacked out, and there were at lease 10 cops in there. While they were giving the presentation, I had P.E. Being the dumb 12 year old I was, my friends and I thought it would be funny to take the Lazer pointer I had and shine it through the door of the gym into where the presentation was going on. 

So, we did, we got a good laugh in, then we went back to changing into our PE clothes. About a minute after we shined the light, a cop bursts through the door and ask, "who has the lazer pointer?" Being the closest one to him, he makes eye contact with me first. I immediately fess up, nearly pissing and shitting my pants. What makes this worse, was that I wasn't even wearing pants for me to piss in, I was just in my underwear. 

So, here I am, getting a lecture from a cop saying how he thought it was a gun or something, and that I need to think before I act, all the while I'm in my boxers. Great.

Oh, and happy 4th of July 'Murica

Can you provide a brief rundown of the text in within 3 sentences?
