OK.

So, how do they know to shoot *THIS* guy over here and not *THAT* guy over there?

The US hasn't yet been hit by suicide bombers yet but there have been several mass shootings that have been stopped by armed citizens. There have also been several bombers in Isreal stopped by armed citizens and, as previously noted, the terrorists were forced to change tactics when they originally started attacking Israeli schools with gunfire and were repeled by armed citizens. So it seems armed citizens do prevent/stop some mass attacks and more importantly, no one has cited any negative effects of arming citizens so why not give each citizen the choice to carry or not?

All this is moot in Calif anyway as only well connected politicians and celebrities are granted permits to carry weapons.
