It just isn't that black and white though. Cops don't only injure/kill criminals and gang members. Many are injured or killed as a result of police responding to a domestic incident. What about an elderly man with dementia or a teenager with schizophrenia? What about people whom, by little to no fault of their own, are unable to follow the commands of an authority figure in a potentially highly charged situation? What about kids hit with a ricochet bullet from a cop's gun? Or a toddler girl getting mowed down during a high speed chase? Or a little boy not realizing his toy gun would be perceived as a threat? Would better training prevent some tragedies from occurring?
When people are dying - for whatever reason - shouldn't their deaths be scrutinized to see if there are measures that can be taken to ensure no one else dies as a result? When we know better, we can do better. These people are forced to make life and death decisions in an instant - so what resources, what training, can we provide to avoid senseless deaths? What would have happened differently had the officers who killed the 17 year old girl in Texas had specialized mental health training, or were taught to shoot to disable, or used a less lethal means of bullet?
While I, in theory, support those who go above and beyond to keep our communities safer I also cringe at there being no oversight, no accountability, and little in way of punishment even when obviously deserved. Anyone can succumb to abusing the power and trust bestowed on them - especially in a demanding, highly stressful, and dangerous job. Questioning why, and what could be done differently, isn't the same as bashing the police, armed forces, firefighters, medics, etc.
