I’ve seen a lot of people on this site make comments that terrorism is now legal in the Untied States or asking if it’s now legal for them to storm the capitol and other such nonsense.

No, pardoning someone does not change the law. A pardon just means that individual will not be punished for that specific crime. It doesn’t mean that individual is allowed to commit further crimes or even the same one again. It doesn’t mean the crime is no longer illegal. It doesn’t mean future offenders are guaranteed a pardon. All it means is that individual is forgiven for those specific actions by law.

If you forgive someone for lying to you, that doesn’t mean that for the rest of your life they and everyone else has permission to lie to you.
