This is more or less why Trump is a bad client. He is constitutionally (wince at bad pun) incapable of following this advice. There's a reason, which is that his own style has worked for him over the years. He sees only the positives of the approach, and doesn't see how his style put him steps away from bankruptcy court in the 1990s. He chalks that one up to bad luck, and his recovery up to his own skill.
Here, he doesn't see the difference between the Feds and all the lawyers he has either paid off as a cost of doing business, or beaten in court. He sees lawyers as a sub-human species of mendicants to be paid when they are useful, and derided when not. He can't grasp that, this time, he's playing against the NBA All-Stars with the best pickup team he can assemble. He figures if you throw enough money at the problem, you get acquitted the way OJ did. That, of course, was because OJ had the NBA All-Stars on his side, playing against the junior varsity in a local prosecutor's office.
This result is a hazard of an inability to learn. The problem is that we all may suffer the consequences. His fallback strategy is to delegitimize the court system, and incite violence. I'm not even sure it's a strategy, in his case. It's just what happens when someone talks the way Trump does, and fools follow.
