Card Counting

I was curious about card counting and found this on WikipediaUnited States[edit]

Card counting is not illegal under federal, state, and local laws in the United States as long as no external card counting device or person assists the player in counting cards. Casinos object to the practice, and try to prevent it,[22] banning players believed to be counters. In their pursuit to identify card counters, casinos sometimes misidentify and ban players suspected of counting cards even if they do not.[23]

Atlantic City casinos in the State of New Jersey are forbidden from barring card counters as a result of a New Jersey Supreme Court decision. In 1979 Ken Uston, a Blackjack Hall of Fame inductee, filed a lawsuit against an Atlantic City casino, claiming that casinos did not have the right to ban skilled players. The New Jersey Supreme Court agreed,[24] ruling that “the state’s control of Atlantic City’s casinos is so complete that only the New Jersey Casino Control Commission has the power to make rules to exclude skillful players.” The Commission has made no regulation on card counting, so that Atlantic City casinos are not allowed to ban card counters. Being unable to ban counters even if detected, Atlantic City casinos increased countermeasures.[25]
