It seems that we want to think of a world that is logical and populated with verifiable facts. However, the world of the lawyer is fundamentally illogical (as are most humans most of the time) and facts only exist when either agreed to by the parties or determined by judge or jury. As a result events that you or I would consider to be unquestionably true may end up being not facts. I have seen this in supreme court opinions, appeals, and bench (judge-not jury) cases.
Sony knows this well. They have tons of money to throw at lawyers. Generally speaking, the more money spent, the more likely you will win.
The word "justice" is never used in law school.
