Though there is no way to guarantee perfect safety, I have found that by avoiding places which attract crowds you can reduce the probabliity of a bad encounter. I NEVER go to movie theaters anymore. I rent or buy a DVD and watch a film at home. (Watching a great film in bed with a loved one is more fun anyway.) I avoid shopping malls, concerts, dense neighborhoods, freeways, etc. Yes, you sacrifice some enjoyment and social engagement, but there are always trade offs... There will always be a certain percentage of people who are violent or mentally disturbed. There is no way to completely avoid that. So try to take the road less travelled - enjoy the scenery and the peace and quiet.
