Let’s all be a bit careful.
Some of the “benefits” aboriginals enjoy are theirs by treaty right; the same sort of “right” we have to recognized borders with the USA.
Some other benefits are what I would call punitive. They were “awarded” by judges who decided, with very good reason, that we – mainstream Canada – brought “dishonour” to the crown (that’s the expression they use) because we lied and cheated in our dealing with aboriginals, even as we fully understood that’s what we were doing.
I agree that there need to be tight, tough “border controls” between Akwesasne and “Canada.” I do not think we should dispute the “right” of aboriginals to have duty free cigarettes on their “sovereign” land; nor should we dispute their “right” to sell those cigarettes – on which taxes and duties have not been paid - on their own land. What we should not tolerate is anyone possessing, for any reason, those cigarettes, the ones on which the taxes and duties have not been paid, anywhere on “Canadian” territory. Thus, we need a new “border” at which every person, every vehicle and every boat attempting to enter Canada is stopped and searched and where all untaxed items are either confiscated or properly taxed.
There’s nothing terribly wrong with Mohawks administering Mohawk law on Mohawk land; there is, equally, nothing at all wrong with Canada administering Canadian law on Canadian land; what’s sauce for the goose, and all that.
Aboriginals have some rights and privileges; Canadians have some, too. It’s time to clarify both rights and duties.
