If he'd used subsonic .22s and kept the muzzle inside the window none of this would have happened

A silent wrong is as wrong as a loud one. I one cannot do firearms discharge in the area because of the law one should comply, also understandable in this case, one should get a trap or simply call animal control. Also check if a air pellet gun would be ok to use. Some 22's are very effective but
anyway caution should be used as if it was a firearm. I see many houses close by.
