The man definitely can't be caught today.
But he won't be short of credit for this.
However, good deeds don't cancel out the bad—that he played the hero today doesn't erase his past.
Hou Wen has already reported him, and the recordings are all there; Yao Jinsheng's name is already well-known in the city.
Even if he isn't captured today, he will be eventually.
The most challenging part of this matter is that the guy got involved in this case.
This case is meant to be used for exemplary positive propaganda.
If the one who had just replaced the hostage had been Director Jia or Song Guanchao, it would have been a tremendous boon.
System insiders, to save the hostages, volunteered to swap places, faced danger without fear, and killed the armed criminal—what excellent propaganda material that would be.
But it just had to be Yao Jinsheng.
That makes it unsuitable for public dissemination.
At least this part can't be publicized.
