Tails has a very specific use case, very few people need anti-forensics.
I suggest looking into Whonix[1] if you want something that you can truly use for privacy. It is also much more secure than Tails by design, and does not have any limitations like locking down the root user account.
Summary from GitHub:
"Whonix is an operating system focused on anonymity, privacy and security. It's based on the Tor anonymity network, Debian GNU/Linux and security by isolation. DNS leaks are impossible, and not even malware with root privileges can find out the user's real IP."
