I might not feel the struggle like some here do, but I understand it. I just totally disagree with the methods being used to deal with it (not that they are achieving anything except alienating about 50% of observers).
man (allegedly) passes counterfeit bill => man arrested and resists => man dies after rough treatment from cop => society goes apeshit
Do you not see how crime begets crime? Ask yourself again what initiated it. Then ask yourself whether the facts are clear. Then ask yourself if the reaction is justified. And if you answer yes, then you're right, we simply disagree.
I'm a Hendrix fan, he was singing "Why'd you burn your brother's house down?" in 1968...
I'll assume much like your knowledge of America, your understanding of techniques used by cops to subdue criminals is also probably from the same place, your warped mind rather than anywhere else.
I've done police training, when I lived in the UK I trained to be a voluntary police officer and there are plenty of options that do not include holding your knee on someones neck for 8 minutes. To say that this was "rough treatment" is naïve at best and complicit at worst. I'll give you the benefit of the doubt. Leaving cuffs unlocked is an easy way to subdue someone, the impact of pain and the way that it impacts can generally take the biggest of people down as they will continue to cut into wrists until subdued. I've had it done to me and I can tell you it hurts a lot and almost forcibly makes you go to your knees. Even if they are allowed to use knees (like they do in Minnesota) I highly doubt the training includes retaining that pressure for 8 minutes. The dangers of doing so can be fatal (and were in this instance). Hide behind the technicalities of what he finally died of, if you want to do that then cancer kills very few people and minor ailments kill a lot more as cancer patients technically die of many other things as the thing that finally killed them but it was the cancer that weakened them to that point much like the knee to the back of his neck. You are almost excusing the act by stating that he died because of other conditions regardless of what the cop did.
The other TV pictures (prior to George Floyd going to the cop car) suggest that he was not resisting, there isn't any TV images of when he was taking down so its hard to tell, but frankly this guy was not a murder suspect, he was being arrested for a petty crime. Even if he'd used a counterfeit note, how would they know if he was the counterfeiter or an unfortunate person using said currency that any of us could fall foul to.
I agree that looting is disgraceful but not all of this is looting, there are peaceful protests going on all around but you don't seem to realise what this is all about, its not even really about George Floyd anymore, that was the trigger moment, but ultimately years and years of inaction to try to bridge a racial divide is what it causing this, not only police treatment but economical and social divides.
