Anyone who is surprised at this isn't paying attention.
There's several factors involved. His cultish following and compliant judges with novel interpretations of law, certainly. But the fact that someone with a lot of money to spend and/or with powerful connections can avoid or delay consequences for their actions is nothing new. Look at the whole concept of cash bail. In some jurisdictions people accused of crimes spend months, if not years sitting in a jail cell waiting for their trial. Not because this is what happens to everyone, but because many people have no financial resources and cannot afford even the most insignificant level of bail. Many will plead guilty just to get released. Meanwhile they've lost their job and have a criminal conviction on their record and have trouble getting a new job. But if you have a few million or billion in the bank, bail is seldom going to be a problem.
Access to lawyers is another obstacle to equal justice. How many people who are reading this article have a lawyer? I have used a lawyer a couple of times in my life, but I don't have one in my smartphone contacts (I almost typed "speed dial"). If I was arrested I would need to use my one phone call to call my wife or other family member and ask them to Google "criminal lawyers in Lincoln NE". And I'm not poor. Even so, I would quickly drain my bank and retirement accounts to pay for any kind of defense. This doesn't just apply in criminal cases. Bringing suit in civil court is expensive. An ordinary person trying to sue a big company or a wealthy individual soon finds out how expensive delays can be. This is how people like Trump are able to avoid paying contractors - they don't have the resources to outlast the myriad delaying tactics. The delaying motions don't even have to be reasonable, but unless they're completely frivolous the judge has to consider them, and eventually the plaintiff runs out of money. Of course there is pro bono attorneys and public defenders exist of course, but many of them have such large case loads that they are no match for the gold-plated lawyers that billionaires have on retainer.
Trump's escape from any consequences for his actions shine a spotlight on a problem with our legal system., but it's not new. And in nine days he will be in charge of the federal law enforcement apparatus, and has promised to use it to go after those he perceives as his enemies. Maybe it's just bluster, crazy talk to gin up support from his rabid base. But is that better? Marginally.
But just the threat of retribution has inspired some to comply in advance.
