Input: Text: so my roommate purchased a new realistic looking ak-47 bb gun. the orange tip was painted black because the person he purchased it from regularly used it in the airsoft arenas where an orange tip can easily give away your position. so i tell him that he should show it to our friends and he takes a picture and uploads it to his snapchat story. about 20 minutes later he receives a call from the police department saying that they saw the snapchat and need to meet him about a block away. he goes over expecting to just tell them it was a fake bb and is immediately arrested and swarmed by 12 cops. the police open his locked iphone with some sort of device and then proceed to pretend to be him and text one of the other roommates in our house to bring the gun. they book him and take him away and tell us to bring the gun to the station, because bringing it a block to them would cause a scene and scare people. we package the gun in it's original box and drive it over to the station where they tell us that they'll check it out in the car. after that everything went smoothly. they took some pictures and released him, but they revealed why it all happened. apparently snapchat scanned the photo he sent out and detected a gun in the photo. since we were near a college campus it immediately alerted police who caused this scene. what's even crazier is this was all done within the comfort of our home, and in no way was the gun being shown outside or being used/shot in anyway. what a night....

 

edit: orange tip was painted black, not orange. xd

edit #2: not sure why you guys think i would be lying about this story, but i dug up this article from about a year ago that confirms some things that happened last night.
