I love ethical dilemmas like this one (on tonight's Lethal
Weapon), which illustrate my point that morality is an illusion,
and there is no naïve 'right' vs 'wrong', only legality, ethics,
cosmoethics, karma and consequences.
The sheriff head is blackmailing the police head over a case
many years ago, where a child rapist killer was going to walk free
because a corrupt cop had secretly compromised the DNA evidence,
and the current police head (then the detective in charge of the
case) had to secretly re-compromise the evidence to 'frame' the
(actually guilty) child rapist killer, to prevent him from walking
free.
Although technically committing a crime by tampering with
evidence, but his selfless-yet-illegal actions (arguably an act of
self-sacrifice, or at least self-risk) arguably saved many
potential children victims.
This illustrates my point that legality, morality, ethics,
cosmoethics are all separate and not always necessarily in
agreement, it's case-by-case, and only the pitifully naïve moral
absolutists / objectivists think there is always a simplistic
'right' vs 'wrong'.
