[extropy-chat] When Did (or Do) People Start Locking Doors?

[Fred C. Moulton]

One of the items that was of value and more widely owned in some parts
of the country were hunting rifles and shotguns.

In addition to locking doors of a home, it is interesting to consider
when locking doors of a car became more widespread.  I can remember a
time when cars were typically not locked in store parking lots.  Also
many of the older models did not have the alerts to notify you that the
headlights were on and thus it was not uncommon for people to walk by a
car with the headlights on and to open the door and turn the lights off
and then continue on.
