In reference to the IR I take it to mean to impinge is to touch the surface of the IR or to encroach upon its borders where a warning is sufficient to alert the offender to back off lest he/she moves in too far or at least have them understand where they are headed whereas a violation gives the idea that someone has gone too far.
There is no such distinction with the Inalienable Rights. You have either broken the IR, which requires punishment, or you have not, and no such punishment is warranted. There is no such thing as "encroaching on its borders". That's weasel-wording, and rules lawyering.
