Re: I don't understand this
Password sharing is one thing, and a measure of both stupidity and contempt of security.
Looking at porn: fine. MPs are, vaguely, in the most broad sense, sometimes passably human and therefore looking at porn is just fine with me. Of course, the rabid god-botherers, of which there are a number of them in the list of MPs, may feel otherwise but these probably have more "deviant" (in their eyes) porn habits to hide therefore may not shout too loudly just in case. Lithographs of victorian ankles included (thank you, Daily Mash, for this one!)
Looking at porn on a parliamentary system? The same system which the MP has access to material of national importance and possibly national secrets, is a thoroughly stupid, braindead thing to do. If it's a cache of images and possibly videos then I would be reasonably lenient however it's unlikely to be this and the morons are probably just browsing porn sites, using Internet Explorer. Such sites are likely to be only marginally less targeted by malware than "warez" sites and the click-bait-trash "listicle" and "article" sites which tend to be 85% advert, 12% white space and maybe, just maybe, some content squeezed in there somewhere.
MPs, and parliamentary staff, are meant to set examples to us all. If we fiddle our expenses we get fired and the tax man and therefore the courts take a very dim view of the situation. If we bribe people or accept bribes it becomes a criminal matter. If we violate security through providing privileged access to those that shouldn't have it we're likely to, at a very minimum, be given a formal verbal or written warning and in some cases, instantly dismissed. If we browse porn on work systems we can expect likewise.
MPs, on the other hand, seem to feel that they are above all of this and any attempt to make them more accountable, or to enforce more accountability on them (one of the EU's aims) is considered a bad thing. A very bad thing indeed.
