Question

"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?

Answer 1

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.
