They are suing for unlawful use of force, the officer in a confrontation with a man who had been shooting (active shooter) and was not putting his weapon down (and who was trained in how to use them BTW), defended himself. It is up to the POLICE to decide what type of a call it was (as if there is anything called a "welfare check" anyway). An armed, drunk and on drugs, combat vet shooting a gun is NOT a Welfare Check. 

Are there things that could have been done differently and perhaps better, of course (DUH). But does it make this Gold Digging family entitled to 7.5 million taxpayer dollars  - Absolutely NOT (DUH).

And your "wisdom" or "time on this earth" will mean nothing in the "legal" process.
