"how many of these incidents happen that get thwarted by competent security?"
It might be hard to tell since many it's hard to count the ones that were turned away by the right people just giving them the stinkeye, good physical security, demonstration of competent control over things like traffic where everyone has to pass multiple even soft checkpoints. Eventually they give up or the window of opportunity closes.
But _even then_ , someone will fill an inside straight if enough hands are played.
