Will Trump be arrested? I don't know, but what I do know is that it's important that those who break the law no matter how much power or money they have are held accountable for their acts.
Too often, rich and powerful lawbreakers are able to escape accountability because of their wealth and power. This does no one any good. Instead, for our country to succeed we need to hold lawbreakers accountable in peaceful, just ways via the courts.
If you don't like the laws, work peacefully to change them, but don't allow the takers in society to abuse the laws in ways that harm and hurt a good society. Onward.
