Mystery images!

A couple months ago various travels took me within a mile or two of the location where an important Supreme Court case concerning freedom of speech originated. Naturally, I took the opportunity to do a little side trip to see the place and take a few pictures:

The question

Which Supreme Court case was this? (Or, where were these pictures taken?) I’ll give readers a little time before I make a new post giving the answer, unless someone knows or manages to guess the answer.

A few hints

The first hint is barely a hint if you know much about me, but it seems worth mentioning for the benefit of readers who don’t. The second hint may be quite helpful if you’re familiar with well-known First Amendment cases and their holdings. If you’re not, I doubt it will be of much use. The third arguably trivializes the problem of answering the question — but only if you choose to use the business names in the picture while trying to figure out the answer.

• My transportation capabilities in the Bay Area are limited to foot, train, bus, and bike.
• The case in question had, and to an extent still has, special relevance in California.
• If the previous pictures aren’t enough, here’s a completely different view of another area at the same location.
