Obviously the two things are not connected

Why would they be?  One person has obviously done wrong, while the others are, just as obviously, in need of leniency because they're from a different culture.

It's not that I care about either case, I really don't.  What the Brits do to each other really shouldn't matter except as a signpost to show where we're going. If they want to incarcerate a single mother because she doesn't say nice things, fine. If they want to let obviously racist foreigners beat up their white folks, I guess that's okay too.

It's only the juxtaposition of these two cases that bothers me.
