What could Tommy do? Wasn't don wrong in his choice? (Mafia: The City of Lost Heaven)

I decided to test the glass greenhouse on the roof of the hotel, which had to be blown up after the race. And found out that they are not broken, while spent all the cartridges, the world in general with interactivity and destructibility is not friends. But the main discovery was ahead, after Tommy threw an explosive wave on the next building from the window, it turned out that the gangster became a boy for whipping, the truth of which and no one wants to beat, apparently even decent cops he causes only pity. Here the fact is that he can not hit for example the butt of the machine or the handle of a cop at the back of the head and stun so, can not strangle the tie, can not cut off the hook in the jaw or throat, can not take next to the lying brick or bottle, breaking it and making a rose in the throat of the policeman, he does not even have a knife butterfly, and he can not even hide the knife. After singing he will still stick on purpose. The question is, could such a not savvy taxi driver become a member of the mafia on an equal level with all, or he still knows something, left without ammunition? After Hitman, it's particularly weird.
