"well sure the police shot an unarmed man who was offering no resistance, but that man did rob a convenience store earlier that day" is an example of which fallacy?

I believe the answer is slippery slope fallacy

Slippery slope is a false argument that conveys that taking minor action would somehow lead to a overblown consequences.
In the sentence above, robbing the convenient store is the minor action and deserved to get shot is the overblown consequences.

Ifeel like this means that we shouldn't just live for ourselves.also, we should respect others as well as people around us. it reveals that everyone should have equalized freedom, no matter their differences: races, cultures, skin color, etc,. we all deserve the same privileges.
