Re: almost any reason....
"they were all police officers. just a few of the 70 odd homicides committed by the US police each MONTH."
And why are there 70+ homicides by US police per month? The first problem is treating the US as one place when it is a collection of states with their own laws and problems and their own racial demographics/issues. Then there are the situations where the homicide is justified. Which leaves the problem homicides what could range from criminal to accidental. But since the officers job is to be in dangerous situations and deal with them it is expected they will have to actually perform their job and it does occasionally mean using one of their many tools.
"Not all perps. not necessarily all Black or Hispanic, just all dead. (now I come to think of it the guy asking cops directions who was shot in the head was white I think)
protect and serve indeed."
Bad cop is a bad cop, which isnt a shock as cops are people and we have plenty good and bad of those. Of 70+ a month (your figures) you give 5 examples of what is plausibly bad cop. But still it doesnt justify the hysteria over guns.
"The merkin sickness vis-a-vis guns is well documented, we in the free world fail to even register surprise with each passing massacre."
There is a sickness concerning guns. Some people are so pro gun they have a mad idea of the world. And there are some people so anti gun that they are more terrifying than the gun nuts. Imagine doing something normal, any normal activity. Imagine mentioning it to someone and their predictable response being 'dont kill anyone' or trying to religiously convert you to how dangerous the activity is. Now replace that activity with going to a gun range. *UK responses unless they are the few that do it or old enough to have actually done it.
As for massacres, people only really care if its a gun. If its another method people are sad, if its a gun the anti-gun nuts cry out for bans and go on and on. As is often pointed out, the massacres happen where nobody is armed. And then you would want the armed police to arrive.
