These criminals clearly won't give up easily.
The only explanation is that they have realized the presence of a sniper and dare not approach the windows again.
Anyone who's played a bit of shooting games knows this.
If the opponent is hiding inside acting as "Old Six," a strong assault is not that easy.
They might be hiding behind a door, a sofa, or a stairway corner, and any slight carelessness will get you ambushed.
Furthermore, this is very different from a game. In games, most people can hear footsteps, but it's difficult to pinpoint the exact location of the opponent.
But in reality, even the slightest noise can be accurately located by a person unless they're hard of hearing.
Not to mention, in games, there are health bars, while in real life, if someone gets shot, they lose the ability to resist instantly and can only wait for death.
It's nothing like those war dramas where one can still fight to the death after being shot one hundred and eight times.
