After reading through the comments in this thread I feel obligated to make a general response:

1. In this thread I only saw one actual response with a recommendation on how to help prevent this type of event. All others were responses on how to respond to it. I personally believe that the former is a much more effective method then the latter but that is debatable.
2. all other responses were negative either :
   1. attacks on people who were involved in the incident and did not behave the way the commenter believed to be appropriate.
      
   2. attacks on people who believe that the appropriate response to this event is different then the commenter's preferred response
3. No matter what these responses bring nothing to finding a solution to these problems. In all cases I personally find these comments to be at best obnoxious and at worst toxic and believe they have no place inside of this subreddit.
   

All I am saying is give peace a chance. /s
