Definition: Unlike the
common image of a
stranger-rapist in a ski
mask hiding in the bushes,
up to 80% of rapes are
committed by someone who the victim knows.
Date rape is no different from \"regular\" rape,
except the victim knows her rapist. The crime can
be perpetrated by friends, partners,
acquaintances, or dates. It\'s important to
remember that it doesn\'t matter if you know your
rapist or not. If it\'s done without your consent,
then it\'s rape, and it\'s a felony.
