Amen.
Our judicial system protects people with a process, whereby their innocence is a presumption in a court of law, and peoples civil liberties are sacred. However, that process also punishes people for dishonesty, malice, and disrespect for the system itself. If you lie, obstruct, witness tamper, destroy evidence, or do other things to hide the truth, you can be punished for those things as well.
Nobody likes prosecutors that overreach like Starr, whom base their investigations on political vendettas, rather than serious matters of government corruption and abuse. But with that said, it's foolish to tamper with the legal process when you're innocent -- absolute madness. If you're innocent then simply cooperate, and invoke your legal right to remain silent or seek counsel, when in doubt, otherwise play the game like every common citizen has to, or face similar consequences if you don't.
Mueller is simply holding people accountable for tampering with process, which is absolutely part of his duty as special counsel.
