Tactical Scenario: Philadelphia Bus Shooting Video

In the surveillance video shown below of the Philadelphia bus shooting, a group of passengers are trapped on public transportation while two gunmen open fire from the outside. The gunmen were responding to a mother who got into a verbal altercation with another passenger over her disciplining her son.

The shooters were called to the scene by the mother to confront the other passenger in a vengeful manner. Her family members show up armed and begin opening fire into the bus.

Here is the scenario: You are on a public bus and overhear two passengers getting into a verbal altercation. One of the passengers makes a quick phone call and asks those on the phone to meet her at an upcoming stop to deal with this individual. Before you know it, the bus stops, the one passenger gets off and you see through the bus window two individuals approaching holding firearms.

What would you do if you could not get off ahead of time and were stuck on the bus?  What if you are carrying concealed?  Was the verbal altercation enough for you to get off at the next stop and catch another bus if you had the time?

Personally, I would have gotten off as soon as possible considering her threat of calling back-up. If I were caught and could not get off early, I would hope I would engage those individuals in protection of my life, stopping them before they could shoot me. The scenario plays out different ways in my mind. Truly scary stuff.  Travel safely!
