Who said anything about CCW?
A large number of the stories involve citizens retrieving long arms from their homes or vehicles.
Seriously, many of those people saying they would not intervene are the same people who say that police should not exist. Well, in your ideal world, YOU would have to be the one to intervene in violent crimes, because that's how it was intended when the country was founded - there was no LE back then, just private citizens.
Watching out for your fellow man doesn't necessarily mean that you're meddling in their affairs. Some violent crimes simply demand an armed response from anyone who is available.
[not referring to the above quoted OP]If you're handling your AR when you look out your window and see some guy standing over an injured officer about to finish him off, you're telling me that you won't take the shot?
People who use "MYOFB" as an excuse to ignore others disgust me almost as much as the moonbats do.
I don't recommend running into any dangerous situation with guns blazing, but there are times when the people simply have to take things into their own hands. While police officers may be public servants who are paid to do what they do, they are still fellow men, and by-and-large they are good people who are worthy of assistance. If I saw a police officer whose life was in imminent danger from an assailant, and I had the means to stop it with a relatively good chance of success, I would like to think that I would take action.
