Are these PTSD ex-military that were hired to be police?  Their ideas of crowd control have been severely compromised.  People with predominantly civilian experience should be the first hired and trained not people with battle nerves who respond to 'threat' as though they are in a fire fight with no discernment for community context.  That man holding the toy is dyslexic with poor verbal skills... the other man was an employee doing his job.  And, the training should be done by experienced, highly qualified, civilian not ex-military, personnel.   The battlefield context needs to go.
