That would be perfect, I need to be sure (or nearly sure) that they're going to show up, because I will use a special type of weapon.

And I will use a riot suit on that particular heist, not just for my safety, I must protect my family too. I can't let them know who I am, they will not be happy with what I planned.

Just a quick note, when Snake showed up the other times, what he used to escape? An helicopter, a car...don't tell me that he just ran away.
