True Crime New York City - Look through wall at hotel

I'm not sure if this works with all hotels, but I'm pretty sure most of them are the same. Go in a hotel, go behind the counter, duck, and walk against the counter, now you should be using the counter as cover, walk to the right of the counter (toward the wall) and you can look through the wall and shoot through it by pressing left, just like you would do if there wasn't a wall there.
