He shouldn't. Yousuke had one job—stop the criminal from escaping—and he blew it. When the guy ran, Yousuke practically stepped out of the way. He would've made it out the front door if that cop hadn't been there.
Naoto says it's alright, but the fact is, he let him down.
Yousuke suspects the old Yousuke would have delivered.
This Yousuke reached for the side of his belt when the man rushed at him, and still doesn't understand why.
