Do you think the NBA is blatantly fixed?

The officiating and the NBA rules are disgusting!! There needs to be an FBI probe into some of these games that have a lot of action on them. though the playoffs have been entertaining it is obvious to me that these refs have been told to call more falls one way or the other. Such as the worst call in playoff history where Lebron James tripped over his own big Side Show Bob feet and fell on top of the defender, but yet it was a foul on the defender. The ref that called that needs to be fined or suspended.
