"After something happens , it 's easy to go back and take a look and analyze what could have been done in order to prevent it beforehand . That does n't do much good after the crime has already been committed . Most people do n't purchase guns and sit up late at night hoping a prowler comes along so they can blow them away . The gun is there so , if your other measures fail for any reason , you are not defenseless in a face to face confrontation . Heck , there are plenty of cases where criminals are scared off once they realize somebody is home and armed ."
"And there are plenty of cases where criminals are scared off by much less than a gun ."
