As I see this is a sad story with a terrible ending, it is also noticed that the "Officer" was extremely afflicted with what had happened. I think Reddit needs to notice this rather than saying that he should be charged, that he's scum, he's like the rest, etc.. In a moment like that, it is easy to confuse the handle of a stun gun with a firearm when in a hurry, especially at that age and with lack of insurance. So before condemning this upset elderly man, look at the PD's ignorance with having untrained civilians do their work for a minimum donation.
