There's an element of society that's always ready to boycott (i.e., guilty until proven innocent). In the US there are rules of law that mandate the opposite...
There are no such rules and never have been. Anyone in this country can boycott any entity for any reason at any time. US law concerning criminal guilt has no bearing on the matter.
Whether such boycotts are reasonable, justified or good ideas is another discussion entirely. But let's not confuse what applies to those charged with crimes and the freedom to patronize a particular merchant or not patronize that merchant.
...allow me to clarify:
http://legal-dictionary.thefreedictionary.com/Innocent+until+proven+guilty
and note the ending statement
"The people of the United States have rejected the alternative to a presumption of innocencea presumption of guiltas being inquisitorial and contrary to the principles of a free society." So if this isn't a
rule, then I don't know what is...
Your link clarifies nothing. It relates to criminal charges/trials. The presumption of innocence isn't a "rule," it's law with respect to criminal charges/trials.
...Incidentally, I haven't noticed any indication so far that this subject will be handled as a civil vs criminal matter...
It's neither civil nor criminal. It's a labor relations matter. The only thing that's happened is attempted union organizing accompanied by a public relations effort. No reports indicate that charges or a civil action have been filed.
You seem to have missed the point. Your initial post, in response to those who would boycott, stated that there are "rules" against a presumption of guilt that ought preclude such a boycott. I pointed out that there is no such rule with respect to boycotts, which generally fall under "free speech." Legal dictionaries and their entries concerning criminal guilt are irrelevant.
Please note that I have been a customer of B&H since first walking into its store in 1976 and continue to regularly patronize it even now. I have not reached any conclusions about B&H practices from news articles about the organizing effort nor am I supporting or participating in any boycott of the firm. It's important, however, especially for an international audience reading APUG, to be clear that the US has no "rule" against anyone reaching any conclusions they wish and boycotting any firm they see fit to.
