Indian casinos are, at least technically, on Indian Reservations.
They are "sovereign states" and are NOT compelled to conform
to State ~ or ~ Federal laws.
I personally KNOW (as unmitigated fact) of a Card Counter who
was severely beaten at Foxwoods, about a decade ago. The irony
was that his brother who is an attorney in Hartford, had the task
of visiting him in the I.C.U., (where he was recovering from internal
injuries and multiple fractures), that he had NO legal recourse.
Some Indian casinos in California, have been caught "red-handed"
[no pun intended] cheating the public - without consequence.
The most amazing of which was one tribe that admitted to using
MARKED CARDS, but refused a California attorney a refund
of the $74,000 that he had lost.
Last year I was detained for hours by casino security staff, with the
assistance of a State Police detective. Yes, Indian Tribes always
have the option of using OUR courts, police, etc. - at THEIR discretion.
