VIDEO is in here : http://conservativevideos.com/2013/11/sick-game-thugs-violently-playing-innocent-pedestrians/ How would you respond when you see someone does that to someone else ? What is your best approach ? How are you watching your back ? (I used reflection such as glass, car windows, mirror ... anything that allows me to see what's behind me and of course check over the shoulder often) Any questions that you wanted to ask ? Any suggestions you may have ? What do you have to say about that ? Does that video teach us anything ?
