Input: Text: this actually happened yesterday evening at about 6:00pm. some friends and i were shooting empty beer cans up on the roof of my house with a bb gun (the classic [daisy red ryder](http://www.daisy.com/node/1)). i accidentally cut open the bottom of my foot on a piece of metal paneling, so i got off the roof to grab a bandage. when i came back outside, the first thing i heard was “put your fucking hands up!” and a semi-automatic rifle barrel was pointed at my face. then about a dozen more cops raided my house and backyard from all sides, pointing their handguns at us while my friends and i stood there frozen and confused with our hands high in the air. turns out someone was driving by and saw us standing on the roof with what appeared to be a rifle, and the cops thought we were on a shooting rampage. luckily i live in canada so no real bullets were fired.

TIFU by having about 12 cops storm into my house with their guns drawn.
