Sorry if this is the wrong forum. But i was interested in buying a tactical mindset type of book, if you want to call it that. What i mean is just a book with information about what to look for when entering a room in a house or a restaurant or places like that about safety precautions and what type of people to look out for. I am sorry if this is vague but i am having a tough time wording this. For example. In the first Bourne movie when he enters the bar/restuarant he is completely aware of his surroundings and can tell who is left handed, who can hold their own in a scuffle. Again, my apologies for this odd question but i feel that i should have general knowledge of this.
