Sadly times have changed. New norms are being formed. One of them should be that everyone carries an Individual First Aid Kit. These are made for serious trauma. It contains no band aids. The one I carry on my person, all the time when I'm out and about is 2.5" tall, 4" wide and 6" long. It can easily fit in a pack or purse or a cargo pant pocket. It contains an Olaes modular bandage,  a couple of packets of Celox hemostatic agent, a SWAT tourniquet,  and some gloves.   
It can be used to stop major bleeding due to a work accident (accidental amputation) or a major traffic accident. It doesn't have to be a shooting or bombing.
Although an IFAK is made for YOU (hence everyone carrying one), if you need to use one on a loved one, at least you'll have what you need right there at the right time.
