Being arrested, even if never convicted, even if never charged with a crime and released with a hug and an apology, will have long-lasting negative effects on your life. For example, a citizen of a Visa Waiver Program country cannot travel to the US visa-free for the rest of his or her life if they have ever been arrested. They have to apply for a visitor visa and convince an immigration officer that they deserve a visa. Just a simple mistaken identity arrest can make the rest of your life difficult and there is nothing you can do to fix it, you just have to endure it.

It's almost become that arrested is conflated with guilty.

For a professional, being arrested for a major crime in America is a life ending event.

Proving one's innocence once the powers that be have determined one to be guilty will cost hundreds of thousands of dollars, will almost certainly mean loss of job, family and friends, etc. And you might still go to prison for the rest of your life anyway.

> This whole line of "what could go wrong!?" starts from a much deeper sickness in the way Americans view the criminal justice system

The sickness is in how the criminal justice system works. Jury trials are a rare edgecase, most detminations of guilt are made by DAs. For most people in this country, being arrested and charged means you will be pushed into a plea deal and those that fight for their innocence face retaliatory harsh charges and sentencing.
