The author doesn't even touch on it until one sentence all the way to the end.
> The ability for police to remotely kill suspects raises due process concerns. If a shooter is holed up and alone, can they be qualified as an imminent threat to life?
There have been lots of quotes by the police about how they "didn't want to risk the life of another officer", but no quotes I've seen about "the gunman was about to escape and go on to hurt others". Why wasn't the suspect containable? Why don't any of the journalists raise this issue, either in their interviews or articles? Hopefully this will eventually all be public as part of the investigation, but the public conversation about this is pretty much useless right now.
The comparisons to the military are not helpful:
> Brown raises an obvious question that the US military has grappled with: If a shooter is holed up in a building, who do you send, a person or a bot?
Unlike the military, the police operate in an environment where simply containing the suspect and waiting him out are very viable options.
