These arrests have all been deemed "process charges" by the real news media. The #FakeNews asks the illogical question "what are they covering up with their lies." Of course, this question is disingenuous. The question presumes there is guilt of anything.

LEO are trained to get you to lie or incriminate yourself somehow. If your testimony is deemed unbelievable, and you also say "I did nothing wrong," then the "logical" conclusion is that you actually did something wrong.
The right to not self-incriminate is absolutely huge! Many will generalize: "if your answer would self-incriminate, then you *must* be guilty of something! This is not accurate at all. If the answer given could possibly be the only crime (an inaccurate statement, for example), then refusing to answer would be to avoid committing a crime!
Don't talk to police.
Don't talk to any law enforcement officials.
Statements should only be made with counsel present.
We have a 5th Amendment (for now, anyways), use it. "At the advice of counsel, I am invoking my right to not answer."
There is no law that requires you to remember something. The answer "I do not fully recall" is a perfectly valid and complete answer.
The right to not self-incriminate is not limited to crimes in the past, it also includes potential future "crimes" such as accidental inaccuracies in testimony.
What you think is an inaccuracy and what LEO will describe as an inaccuracy are two different things.
