I am pretty sure this short story/novelette appeared in either Galaxy or Astounding in the 1950s; it was definitely in a magazine and not an anthology. (It isn't Telek by Jack Vance, although it sounds like it.) The place is Earth in the near future and the main character is a 'TK' a telekinetic. TKs are known to the public but feared and loathed. At the beginning of the story someone tries to run him down with a car while shouting "TK! TK! TK!" Unfortunately, that is the only detail I can remember. The story somehow involved crime; it had a real noir feel to it. The interior illustration that appeared with the story showed a man with a gun. Any help is appreciated.
In this story telekinetics or "TKs" are a part of society, but not feared as far as I can tell. However, the narrator tells the story of himself being forced into discovering who is stealing from a casino by the TK lodge he belongs to. During this job he is strong-armed by the casino bouncers after being revealed as a TK:
TK!" somebody yelled. He might as well have screamed, "Fire!" the way that mob of gamblers scuttled away from the table.
In another event he is almost run down by a car:
At last I went down the ersatz wooden steps into the neon-gashed night and started across the nearly deserted main drag toward the motel where I had registered. A powerful turbine howled as a car pulled away from the curb, perhaps a hundred yards up the way. His lights came on and snapped up to bright. I had a perfect flash of PC—I do have moments of it, no matter what the Lodge thinks. The car was going to take a dive into the fountain pool in front of my motel. But it sure didn't act like it. I froze in the middle of the road, hearing rubber scream as the driver floored the throttle and hurled the automobile right at me. He might as well have been on tracks. There was no place to go—I was in the middle of a six-lane boulevard, and could never make either curb before he ran me down.
The story has a strong 1940's--1960's gangster feel, including the argot of the times and caricatured bouncers, casino owners, hustlers etc.
