Muckers?

1.

The incidence of muckers continues to maintain its high: one in Outer Brooklyn yesterday accounted for 21 victims before the fuzzy-wuzzies fused him, and another is still at large in Evanston, Ill., with a total of eleven and three injured. Across the sea in London a woman mucker took out four as well as her own three-month baby before a mind-present standerby clobbered her. Reports also from Rangoon, Lima and Auckland notch up the day’s toll to 69.

Background: ‘mucker’ is an Anglicisation of ‘amok’. Don’t believe anyone who says it’s a shifted pronunication of ‘mugger’. You can survive a mugger, but if you want to survive a mucker the best way is not to be there when it happens.

Out there: all those millions of people . . . Like looking up at the sky and wondering which of those suns shine on beings like ourselves. Christ: when did I last look up at the night sky?

He was suddenly appalled These days, a great many people never left their homes at night except for some specific purpose, when they could call a cab to the door and expose themselves for no longer than it took to cross a sidewalk. It wasn’t inevitably dangerous to wander the night streets of the city – the hundreds of thousands who did still do so were proof enough of that. In a country of four hundred millions there were two or three muckers per day, yet some people acted as though they couldn’t get past the next corner without being attacked.

“In my country,” Jogajong said, “a man who thinks like you goes voluntarily to join his ancestors. Or used to in the old days. Now, the usurper Solukarta has copied your Christian habits and closed that way of escape. Which is a reason why we have so many muckers, I think.”
