You're right. This isn't about platforms, this is about following the law and IMNSHO, DPD did not do that. Without any information except what has been reported on this and other websites, it appears that after preventing his ability to move, cordoning off the area and attempting to negotiate for hours, they made a judgment call to end his life. He may or may not have been a threat to the general population or to the officers on scene. Regardless, the power to end another life is precisely what is at issue in the mind of the shooter, the mind of the police and the mind of every US citizen that is aware of the increase in police violence. Civilian police forces should not be in the business of killing people and that's what the constitution is talking about with the phrase "due process". It's the military's job to kill people and the military are not peace officers, they are war officers. The distinction is important and bound by law, but increasingly ignored by police forces with the aid of the federal government. The militarization (not just a FUD word, but literally, the conversion of peace officers to war officers) of police forces is the issue and the reason why there was a protest in Dallas and the reason why Johnson went mental and decided to kill cops there. Assassinating him (look up the definition) only reinforces the feeling among Americans that the police are out of control. Did he deserve to die? Most likely, but it isn't the job of police forces to determine that. That is what a judge and jury are for and one of the reasons thirteen colonies because thirteen states after a long and bloody war. If there is not a strong legal reaction to DPD's use of force in this way, the situation will get worse, not better. If there is not a show of restraint by those who are sworn to "serve and protect" there will be escalation that leads to civil war. The USA has already had one and we should do everything we can to avoid another because it was the single great cause of American deaths, ever. If you say you care about people, then you should care about upholding the law, especially for those who are given guns by the government chosen "by the people".
