Police do not place themselves in the line of fire to justify killing.  That is ridiculous and shows your lack of respect for suggesting that meaning.  No police are trained to confront and control suspects at any cost.  Killing is not the objective.  Killing is the consequence of the approach to apprehension used.  You support it.  Most people support it.  It leads to death.  Alternative approaches to apprehension are possible.  Most police in Britain are unarmed yet they apprehend.  Still don't understand?  Motivate police to used different methods and lives will be saved.

Regarding women and girls abused, I have more care for then than you.  I am willing to suffer abuse in order to suggest pathways to improve society, which you and others scorn because it is more important to you to make feminist points than to encourage interaction pathways that do not lead to unfortunate consequence.
