Here you go.
"In Orlando, Florida, in 1966 a series of brutal rapes swept the
community. Citizens reacted to the tripling in the rate of rape
over the previous year by buying handguns for self-defense; 200-300
firearms were being purchased each week from dealers, and an unknown
number more from private parties. The newspaper there, the _Orlando
Sentinel Star_, had an anti-gun editorial stance and tried to pressure
the local police chief and city government to stop the flow of arms.
When that tactic failed, the paper decided that in the interest of
public safety, they would sponsor a gun-training seminar in conjunction
with the local police. Plans were made for a one-day training course at
a local city park.
Plans were made for an expected 400-500 women. However,
more than 2500 women arrived, and brought with them every conceivable
kind of firearm. They had to park many blocks away, and the weapons
were carried in in purses, paper bags, boxes, briefcases, holsters,
and womens' hands. One police officer present said he'd never been so
scared in his life. [It must have been quite a sight!

]
Swamped, the organizers hastily dismissed the women with promises for
a more thorough course with scheduled appointments. The course offered
was for three classes/week, and within 6 months, the Orlando police had
trained more than 6000 women in basic pistol marksmanship and the law
of self-defense.
The results?
In 1966 there were 36 rapes in Orlando, triple the 1965 rate. In 1967,
there were 4. Before the training, rape rates had been increasing in
Orlando as nationwide. 5 years after the training, rape was still
below pre-training levels in Orlando, but up 308% in the surrounding
areas, 96% for Florida overall, and 64% nationally.
Also in 1967, violent assault and burglary decreased by 25% in Orlando,
in addition to the rape reductions.
In 1967, NOT A SINGLE WOMAN HAD FIRED HER WEAPON in self-defense. In
1967, NOT A SINGLE WOMAN HAD TURNED HER GUN ON HER HUSBAND OR BOYFRIEND.
(No data are available for later years.)
The reason the program worked so spectacularly well is that it was
widely known that Orlando women had the means and training to defend
themselves from attackers. Rapists, being (somewhat) human, they are
learning engines; they took their business elsewhere--to the detriment
of the defenseless in those other locations.
Department of Justice victim studies show that overall, when rape is
attempted, the completion rate is 36%. But when a woman defends herself
with a gun, the completion rate drops to 3%.
Overall victimization studies show that for all violent crimes, including
assault, rape, and robbery, the safest course for the victim is to
resist with a firearm. The second safest course is passive compliance
with the attacker, but this tactic approximately doubles the probability
of death or injury for the victim. All other tactics (mace, whistles,
hand-to-hand combat, screams, and so forth) have even worse outcomes."
