You can keep saying it but it isn't accurate.
Tennessee vs Garner established that law enforcement cannot simply shoot fleeing felons. There are very limited circumstances in which fleeing felons can be shot by law enforcement officers and they all overlap with situations in which the average citizens may find themselves in...for example: You witness a mass shooting and you believe the fleeing shooter will continue to shoot people...that is a fleeing felon you (a non LEO) can shoot. Example 2, you witness masked men exiting a bank with guns in there hands, and you believe they are now using those guns to hijack cars to escape...you (a non LEO) can shoot those fleeing felons. Example 3, you were just ambushed by armed robbers and a shootout occurs...you put one of them down and you believe the second is running for cover to reload, you (a non LEO) can shoot that fleeing felon. 4. You witness a guy shooting a cop as he starts to flee, you (a non LEO) can shoot that fleeing felon. The trick is properly articulating and winning your court case if you are charged.
As an ex LEO, I can say with great certainty that a LEO will get more latitude when shooting fleeing felons, but there is no blanket authorization to "shoot fleeing felons to protect the public" and any situation where a fleeing felon is shot will have to be properly explained (in theory).
Since they didn't charge the officer, this shooting is a definite example of latitude given.
