> The police who murdered George Floyd are in jail, and serious reforms were enacted as a result of their misconduct.
This is probably the highest profile situation that worked out as it should (with the PD firing the officers within 24 hours of the event). Oftentimes, this does not happen. Let's look at several high profile deaths:
Eric Garner - no indictments, no charges.
Michael Brown - County, DA, DOJ all declined to press charges.
Tamir Rice - all charges declined.
Laquan MacDonald - officer guilty of second degree murder, released 3 years in to a 7 year sentence.
Walter Scott - officer found not guilty of murder, guilty of violating federal civil rights. State dropped charges.
Freddie Grey - six officers charged, three cases dropped, three acquitted. DOJ declined charges.
Philando Castile - officer acquitted of manslaughter despite their own bodycam (but to your point, he was charged).
Justine Damond - shot after calling 911 to report being raped. Officer convicted of murder and manslaughter, murder overturned on appeal.
Breonna Taylor - no charges filed, and officials stated it was justified because someone else was firing at them. One officer convicted of negligence after shooting at entirely the wrong home.
Many of the above charges also only came about after significant public protest over PD/DA/DOJ initially declining any charges or denying there was any issue.
> As I write this, there is a real chance the former president will serve jail time after a fair trial.
You are entirely too optimistic. Realistically, at best, he will be placed under limited house arrest.
