What do you do?

What do you do when walking out at night and see very unusual things that may endanger lives, but being outnumbered you walk on and think of ways that could have made a difference.....

I offered up a prayer, hoped for the best and looked around in the morning to see if life had carried on for that person. Satisfied in my heart that any intervention at that point may have turned things upside down and that my safety was at stake at that point.

My training so far has not included this kind of crisis, but equipped with the tools of observation and understanding of what the other person may be going through makes me think that all may not be lost.
