There being less commuting from firearms-friendly places, such as PA and some NE areas, into such places restrictive places as NYC, some number of folks are with their firearms much more of the time, which could result in increased carry time. This could have a gradual effect of more folks finding the possession and carry of firearms to be normal and familiar.
As member sota indicated, in the above post, burglars who used to burgle commuters’ unoccupied homes are now more likely to be encountering homeowners, which may well drive a demand for defensive weapons.
I wonder whether inner-city robbers/muggers, deprived of their usual commuter prey, are commuting outward, into the suburbs and exurbs? Interesting.
