Not justifying it. If you read carefully I explicitly wrote "Not defending the police action". Simply providing context. He was shot after attempted murder, not petty thievery. Does that justify it, no.
The video you posted is another one, not the Chocobar case. I'm not familiar with this incident, but as long as the thieves didn't shoot at her or anyone else, I'd have to say just from watching the 10 second video that the police officer used excessive force.
Unfortunately, BajoCero does seem to be justifying police brutality.
