I took self-defence classes too, every woman should. I managed to resist a mugging while traveling abroad, and a purse-snatching here, ages ago.  I still travel and walk around with a handbag.

I was close by when one of our university mass murders happened. I don't worry about getting murdered while working at a university.

As the Left is fond of telling us, we have a better chance of getting killed in the bathtub than getting murdered by a terrorist, or as Marie Heinin put it elsewhere here:

"the incontrovertible fact is there are very few terrorist attacks in Canada and the United States. That is the baseline diagnosis. A restriction or ban on small household appliances would make us safer."

You and your daughters have a better chance of getting killed by a murderer of women, than by a murderer of Muslims. There are a lot more of the former.
