What Fallacy is this

Person A commits an indiscretion. When called on the indiscretion, person A excuses his action because person B did the same.

Eat Meat... Or Don't.

Roughly 95% of Americans don’t appear to have an ethical problem with animals being killed for food, yet all of us would have a serious problem with humans being killed for food. What does an animal lack that a human has that justifies killing the animal for food but not the human?

As you start to list properties that the animal lacks to justify eating them, you begin to realize that some humans also lack those properties, yet we don’t eat those humans. Is this logical proof that killing and eating animals for food is immoral? Don’t put away your steak knife just yet.

In Eat Meat… Or Don’t, we examine the moral arguments for and against eating meat with both philosophical and scientific rigor. This book is not about pushing some ideological agenda; it’s ultimately a book about critical thinking.

Sounds like the Ad Hominem (Tu quoque) .

Logical form:

Person A did X.

X is considered wrong.

X is not wrong in this case because person B also did X.

If something is wrong, then it's...wrong. Another person doing it does not alter the nature of the action itself; it simply means that two people have now committed wrong. So if it was wrong when person B did it, it is wrong when person A does it too.

This is the logical fallacy of Ad Hominem (Tu quoque); a common fallacy of relevance used to change the conversation from one's wrongdoing to another's wrongdoing.
