weird bug in Cassino, some sort of Wallhack

as the title says, I found some weird bug/glitch in Cassino. It kinda works like an Wallhack. Idk if it's fixable, though.

Nice that u've noticed that Random , and idd sometimes I got shot from the top hotel and I couldn't see from where that come from, it must be then that kind of glitch u talking about !

This is not a glitch since it is very easy to use it and i think a big part of cod players know this spot. It was never fixed by official patches =/

But, no big deal, IMO this is not a very good spot, you have to be at the very end of the window and everybody see you if you stay too long.
