In most mass shootings, rarely anyone fought back. Why do you think that is? We have warned everyone to get prepared in the last month and sadly not one person out of 300 people in San Bernardino returned fire, sprayed mace, sprayed wasp spray or threw a rock. You have got to do something people! Everyone cannot run and hide. Your dreaming if you think a 911 call is going to save you and your family. Just review the U.S. mass shootings in the last 30 years and see when the cops arrived. I paid a visit to two local gun stores and the shelves were nearly empty. We can't just buy them, we must train with them and be confident in our abilities to protect ourselves and our families. Good luck.
