At that time the “Cocaine Cowboys” were still fairly strong and police resources were still stretched pretty thin. No telling how that may have influenced the amount of time given to the investigation. The drug runners will always be a problem in Florida and that takes tax dollars and cops out of neighborhoods.
As far as the “didn’t see nuthin” neighborhoods go, will they ever figure out that their silence is what makes a lot of the violence possible?
Nah, that would require common sense which ain’t so common anymore.
Now look, if you acknowledge that clamming up creates problems, you can’t scapegoat law enforcement. ;^)
