Catch you later, traitor

This book made me extremely thankful I didn't grow up during the Red Scare. It's shocking to learn that the ethical standards of the FBI at the time permitted following minors, harassing them and questioning them without a parent present. I completely did not see it coming that the uncle was the informant, because I expected him as a communist to view the socialist dad in a more favorable light than the anticommunist antisocialist FBI. The uncle, by acting as an informant, is a traitor to fellow communists and any leftists (like the dad) who are trying to make the world better. I found myself exclaiming “NO!” at the main character for choosing to talk to the FBI agent, because anything you say, no matter how positively it paints you, can and will be used against you by law enforcement, by nature of how law enforcement works.
