If there had been good guys with guns, the victims would still be alive.
In these situations the attacker always has the advantage. Sadly, they can unleash carnage before people have a chance to respond.
Now, would knowing there were people there possibly armed have deterred him from acting....?? Possibly.
Unlikely. The videos are out. He got right out of his car and started shooting people walking who had no idea he even stopped his car.
He was stopped by a cop who was on the scene who undoubtedly did prevent many more murders by shooting him right in the face.
I am very pro-carry and wish more responsible citizens were armed.
However, there was little that anyone could have done to react quickly enough to prevent that first group from being slaughtered and likely the second group that was off-camera to the left as he walked out of view. He gunned them down in seconds and they had no cover against a rifle at pretty close range with zero warning.
Horrific. There are demons among us and no guarantees in this life.
