"First Up Against The Wall When The Revolution Comes"

Perhaps, but the OP is indubitably about #1.

Agreed. However, the discussion has branched out into the use of the phrase “Up against the wall” by itself, which crops up in various contexts, and may have different meanings.

I had always casually assumed the Jefferson Airplane lyric was in reference to police rounding up demonstrators (#3); but on reading the rest of the lyrics it seems that it must refer either to meaning #1 or #2.

Ah, memories. At Oberlin College in the mid-1980s, there was a tiny cadre of the Spartacus Youth League. They passed out literature that almost always included the phrase “Smash Reagan’s anti-Soviet war drive,” or the like.

One of my buddies invariably declined their pamphlets, saying, “No, thanks. I smashed at the office.”

Could it be derivative of Shakespeare’s “The first thing we do, let’s kill all the lawyers” from Henry VI, [Part II](The first thing we do, let’s kill all the lawyers)?
