gun laws
In the hotel room, Stevenson says to Wells:
Did you know that you can go into a shop here and purchase a rifle or a revolver, it's perfectly legal...?
He says this as if it's an extraordinary idea which Wells would be surprised to hear, and this is how Wells reacts. However, the real Wells would more likely have responded, 'So what?' Someone living in late Victorian England would have been used to guns being readily purchased legally. It was only in 1920 that gun laws in Britain began to be significantly tightened. Before then, the situation in England wasn't so different from that in the San Francisco of 1979. The writers apparently assumed (wrongly) that the gun restrictions in force in Britain in 1979 had been essentially similar a century before.
