My, aren't we feeling cheery?
And to answer your question, I wouldn't. I would trick the guard into opening the door by faking a seizure, then I'd headbutt his balls and run. After that, I'd need a little more info before formulating an attack plan. Fortunately, I already tattooed the blue prints of the ENTIRE building all over my body, disguised by an elaborate mural with religious overtones. Now all I need to do is find a bathroom. I then break a mirror, and use the shard to cut open the jacket. I then use the shard to view my tattoo and find the best route of escape. But first, I need to change into something more comfortable. I hide in one of the stalls and lock the door. When the guard I attacked attempts to open it, I kick the door open and knock him out. I steal his uniform and weapon, and calmly make my way out of the building, where my mob connection has a plane waiting to take me out of the country.
