>This is unpopular, but I believe it to be true, I think.
Your belief is simply wrong. The risk of dying in a line of duty for cops is quite low, being a LE is not even in the first top 10 dangerous professions. Most deaths are due to the traffic incidents.[0]
>Aaron was a great kid, but the majority of people brought into the station aren't.
Who defines that? Police? Nice circular logic you've got there. Until the court says otherwise they are citizens whose rights should be upheld as much as possible.
Also it's great that US has such upstanding citizens as you, protecting the real opressed minority - policemen. If Aaron would be wearing his shoes, who knows what grave harm could he do to a police station full of armed cops?
EDIT I digged a little deeper and found out that number of police deaths in the line of duty during latest years had been around 100/year[1].
At least 1450 were people killed by police since May 2013[2].
I don't wish that on you but there would be a certain ironical justice if police apologists like you would experience non-lethal brutality themeselves. Maybe then you would learn something.
