major changes regarding self-defense. What are the roles of pepper spray? Is it legal where you are? If one has a knife, how is it legally carried? Is it an automatic (switch), does it have two edges? Is there a better way to be self-aware when walking the streets plugged into an on-line music subscription? How can people in wheel chairs better defend themselves? Are the number of robbery attacks increasing or not? Related to this is how the cashless economy may be causing violent crims to reconsider their target opportunities? Do thugs "case" in-store ATMs and mark users for off-premises attacks? Then there is the whole sphere of SD in your home, esp. if one has no gun. Superior doors and windows, home modifications, safe rooms, remote cameras which "talk to you" when someone is spotted on your lawn, how to read your pet's behavior?
In cars with auto-locks, when is the best time to use the remote? Can one temporarily disable a remote or even the ignition once the car is jacked? What are the best procedures (if any) for picking up hitch-hikers? What are the dangers of giving one a lift, but asks for you to stop off at a convenience store (can we say "sucker getaway driver?"

There's a lot more before anyone even gets around to arguments over holsters.
