More security is cool, but there's still a problem.
"When a young mother in the neighborhood was recently stabbed multiple times in front of her children, a Seal security officer was the first to arrive on scene."
Nothing beats 'being personally armed'. Yes, more security is useful, but in this case, they were just in time to make the report instead of putting the dirtbag into the coroner's van.
Had the young mother been armed, she could have perforated the assailant right on the spot.
