Okay, so lets do some math. If 70% involved individuals armed with fire arms, lets just pull those from the picture, That would decrease our numbers by 70%. Just to keep things simple, lets say that in the US we have 30 police shootings per year, compared to 1 in western Europe. Ignoring police killings involving people with guns, that would drop us to 9. Or in other words, even if you neglect the number of people our police kill who have a gun on them, but still count those for Europe, our police officers still kill 9x as many people as police in Western European countries. So no, I don't think presence of guns themselves account for this disparity. I think our police officers are overly violent.
I agree, the presence of more guns isn't 100% of the explanation. The problem is that people often cite the total numbers in comparison without even addressing it as per capita, and they always leave out the fact that US police are far more likely to encounter assailants with guns. If we have a problem, we first need to be honest about its actual magnitude.
In the US, about 30 people per 10 million are killed by police yearly. It's about 1000 per year, out of about 16,000 homicide deaths. We have ~3,000,000 deaths yearly in the US. Homicide is the 15th leading cause. Police homicide is probably the 100th.
Of the 1000 police killings, how many were justified versus unjustified? Figure out approximately how many are unjustified, and that is the statistical magnitude of the problem.
It's worth pursuing police reform, and not only in relation to killings, but across the board. However, the actual magnitude of the problem of police killings is being exaggerated because videos are now available which weren't before, and because honestly the media is putting a huge spotlight on certain cases.
As I said, I agree, be patient. But as I said, I'm not the one being directly impacted by this. There is a difference between saying "we understand, but please keep the protests peaceful" compared to saying "your rioting is going to cost us the election" or "your rioting justifies the police violence". Telling these communities that its their fault if we lose the election doesn't help anything. Telling these people that they are to blame, not the police, is just going to incite them to more violence. What many here are advocating for is the verbal equivalent of Trump sending federal troops to put down riots in Portland. It just escalates the situation.
The rioting doesn't justify the police violence, but it could indeed cost us the election. Indeed, Biden will still likely win, but in spite of the rioting, not because of it.
The importance of this election cannot be underestimated.
