"Flash Crowd" was a 1973 short story by science fiction author Larry Niven, one of a series about the consequences of instantaneous, practically free teleportation booths that could take one anywhere on Earth in milliseconds.

One consequence, not predicted by the builders of the system, was that with the almost instantaneous reporting of newsworthy events, tens of thousands of people worldwide would flock to the scene of anything interesting—along with criminals, hoping to exploit the instant disorder and confusion so created.
