i missed it

so i'm at work and it was time for my first break.me and a co worker go sit outside for the break..as we step outside we noticed two cop cars in front of building facing each other.I told co worker it looks like they are under an urgency by way they are parked..we dont think much more about it and head back in side.that's when other co workers start to tell us why the cops were there. Apparently a guy was standing around by enter exit doors on inside of store on his phone and had a gun.he didn't threaten anyone or anything just had a gun like it was no big deal while on a cell phone.they said the cops let him go because he had a permit.
So through out the night co workers were telling story of scary shit that has happened in the store years past. there was this one story a co worker told me that a guy all calmly walked into housewares department and opened up a knife and cutting board and sliced his fingers off and walked around the store..crazy huh..lol..
