Domino, Longshot, and Blackcat. Their luck powers will make him trip and kill himself or if he's not dead yet, they can finish him off with their standard weapons ( guns, knives, claws )
As someone already mentioned, it seriously depends on the LEVEL of Speedster one is talking about.
For lower-level speedsters, people with high levels of skill/timing and/or advanced sensory capabilities and/or lower-end reality-warp/luck powers can affect them. Eg, Batman/Wolverine; Spider-Man/Midnighter; Domino.
For higher-level speedsters, no Street character should be able to nab them. They are simply too fast and have too many options of adjusting (eg trajectory) that no amount of timing would work, sensory perceptions would not be processed fast enough, and luck powers would need to be on the more powerful side.
But in comics, Batman can stab Reverse Flash in the foot and Deathstroke can punch the Flash. In comics.
In KMC, no Street should ever be a threat to high level speedsters
Never let anyone else define you. Don't be a jerk just to be a jerk, but if you are expressing your true inner feelings and beliefs, or at least trying to express that inner child, and everyone gets pissed off about it, never NEVER apologize for it. Let them think what they want, let them define you in their narrow little minds while they suppress every last piece of them just to keep a friend that never liked them for themselves in the first place.
And Karate Kid, obviously. Has better feats against speedsters too.
