To step in, or not to step in--that is the question

I feel like I see the question being asked, would you get involved and draw against a bad guy even if they're not focused on, or posing an immediate threat to you rather than bug out a lot, and it feels like the sentiment many CCers hold is that of "not my circus". I understand the fear of getting involved in a scenario where there is no immediate threat to life or of bodily harm, because by getting involved even if you remain concealed, you're still introducing a gun into the mix. Here is a situation where two bystanders/CCers stepped into an active shooter situation, placing themselves in danger when they could have just as easily and more safely gotten out of dodge.The above case however may be an outlieing scenario, and while training and preparing for such things is important a more probable instance we're likely to find ourselves in may not have a cookie cutter bad guy or even a gun.As a CCer, in what capacity would you get involved in a situation where you feel an injustice is being committed?I feel like we have a social responsibility to get involved in some capacity, be it verbally saying "hey, stop that" if not calling the cops from afar and observing. via /r/CCW http://bit.ly/2PfNGer
