Rattled and shaken after seeing open carry in a grocery store

324. No, I think those attacks will happen regardless.

I think open and concealed carry are largely irrelevant to the issue.

(Edit: Naval Shipyard shooter used a duffel bag. Colorado theater shooter used a fire door, and a box in the back of his car, sandy hook, the asshole started shooting as soon as he saw people as he approached the school, etc.)

People planning an attack are uninterested in complying with lawful carry laws.
People who carry out and about legally are rarely in a position to oppose such shooters, if for no other reason than there are so incredibly few of them. (There's a couple examples, but statistically negligible)

It would be interesting if there was a case where someone planned an attack, was seen armed, and ignored, when a simple call to the police could have halted the whole thing.
It would also be interesting to see an example where someone just flat out called the cops when seeing someone with a gun, and that too prevented an attack.

But I see the two issues as largely un-connected.
