Bruce,
Incidents like the Squeaky Fromme one (not to mention Sirhan Sirhan) are the reason the crowds at many political rallies (especially for Presidential candidates) are thoroughly screened for weapons. They're also the reason the President is behind a bulletproof shield at the inauguration, etc.
Surely you're not suggesting that no small-stature woman should be allowed to approach a political candidate because of what Squeaky Fromme did, are you?
