You'll have to Google the "covenant of Gun law". Anyway, the sentence structure is nothing new. You have a list: 1st item + comma + 2nd item + or This is the usual way of listing a series of IFs. Whether you do this, that, or something else, I don't care. I still won't marry you.

The word "whether" introduces an either or statement. "Whether or not you are sick, you are going to school." "Whether they win, lose, or tie, they played well." With regard to sentence structure, the comma is being used to separate a list of items as the previous poster stated. The last comma is to insert a pause and then make the final statement. Hope this helps.

Thank you for your explanation.

Iris, regarding your question about the covenant in Gun Law, I think this is a matter of interpretation. My guess is that we are talking here about a lawman who considers himself bound by some kind of covenant (ie to uphold the law), and resorts to the use of guns ('Gun Law') to enforce the covenant. It is hard to see how he would use the 'Gun Law' to comfort a widow, but, again as a guess, I would say that he would kill the murderers of the widow's husband to provide her some sort of 'comfort'.
