Interesting slant that I've not seen mentioned.
The legislation still has to be passed and until then no-one really knows how much it will affect us, but I think it will be significant.
Recently the Post Office/Parcel Force tried to renage from carrying guns but were told by the regulator that they had to continue.
This could raise it's head again and if what you mention comes about it would stop most second hand private deals dead.
