Playing stupid games did not led to the stupid prize

Quick summary: Call to 911 of a domestic dispute ending with a male shot by the wife. Cops arrive at scene, find the male outside the house, secure him for transport to local hospital and try to deal with the female who announces she has a gun.

Female comes out of the house acting like she has a gun hidden under a sweater.  Makes enough menacing movements that cops open fire ....and miss.

There was at least one rifle involved in the mix. No idea if it was used, but if it was and also missed... holy crap.

I am seeing more and more videos where cops go slide lock and miss the target altogether.

If Spray and Pray done by gang members is bad, how come it is not an issue for police?
