With the recent attack on the Congresswoman and the other people in the grocery store, there were three armed people at the rally. For whatever reason they did not fire any shots.
From anyone who has police and/or military experience, what would you in a situation like this in regards to not hitting someone other than the gunman? If someone was armed, I'm sure they would prefer to take down the gunman, but I'm not sure how many people would want to take a shot and risk hitting an innocent person.
Also, what happens at an event like this if the police show up and there are multiple people with guns? Do they generally fire at anyone who is armed? If you had a weapon for self defense wouldn't you be putting yourself at a risk?
This is also one of the arguments about why police officers don't want guns "allowed" on campuses, that being that they don't know who to shoot at.
I was just reading an article about this the other day and since I don't really know anything about firearms myself I thought I'd see if there were any police or military personnel that knew the answer to my question.
