There are, in my opinion, three main reasons for the
increasing numbers of persons killed by police officers
in this country:
1) mental illness is still widely untreated today, and
treatment facilities are woefully inadequate.
2) It is far too easy to obtain firearms in this country
today. The more citizens that are armed, the more
likely some of those citizens are willing to use them
against law enforcement. Also, red flag laws that
are designed to strip certain persons of their right
to possess firearms due to previous violent threats
or actions are inadequate as well, and vary from state
to state. We need to strengthen our nation's red flag laws.
3) from what I've seen of some recent police shootings
that resulted in the death of armed subjects, I would say
that the numbers of 'suicide by cop' shootings are
also on the rise. I've posted a few videos here of OIS that,
in my opinion, involved armed subjects who were literally
surrounded by police officers, with no possibility
of avoiding capture/arrest, and yet made the decision
to go out in a hail of gunfire by either shooting at or
pointing their firearm at responding officers.
