"the National rifle Association, the nation’s oldest civil rights organization, filed suit against Chicago and San Francisco." Not to nitpick, but the Chicago suit was filed by Second Amendment Foundation and the Illinois State Rifle Association, not the NRA.

"All you people look alike to us."

Taking away rights from people who accept public housing serves to emphasize the existence, and the importance, of those rights among the general population. SF should restrict their speech and forbid them to vote, too. Same rules as a public school, no? I think there is some unconditional-conditions doctrine law on this point and it will be interesting to see how it applies post-Heller.

Until then, the contrast is refreshing: "You can live in public housing and be forbidden a gun, or you can live like a REAL citizen." SF has halfway-houses for people released from prison, and those guys can't vote or own guns. An SF housing project (and I have lived very near them) feels much like a house for people halfway TO prison, so SF might as well apply the same rules.

I was thinking the news reports were just confused for a while but it appears that in addition to the SAF's case the NRA has also filed several suits in Chicago and surrounding suburbs.
