Winbigler v. Warren Co. (IL) Housing Authority. After being educated on the rights detailed in Heller I, Warren Co. changed their policy prohibiting firearms in public housing units and asked the judge to dismiss the case. The key here is that it's Public Housing, and the government (not a private landlord) that was trying to deny Mr. Winbigler's right to keep a firearm in his dwelling.
The Constitution protects our rights from being infringed upon by the government, not another private citizen.
Even though the outcome was a win for Winbigler, the court didn't rule on the constitutionality of the anti-2A lease provision. It just enjoined the housing authority from enforcing it, because the housing authority already agreed out of court to remove it. In the ruling, the court stated
This Order only pertains to the specific lease provisions above and is neither controlling nor dispositive as to any future lease provision that Defendant WCHA may implement concerning possession of firearms or other weapons on or about its property including individual residences.
In other words, the injunction does not prohibit the housing authority from re-instituting a firearm ban. It also doesn't prohibit any other leasing agencies from banning firearms in their leases.
If East St. Louis doesn't back down, the court could make a precedent-defining decision in that case. Otherwise, I agree that such a decision would not necessarily apply to private leasing agencies. Bummer that. Maybe the next case.
And this is why I can't understand why any public building can be made off-limits to the second amendment freedoms.
The freedom to use a bathroom at a state park....
But seriously, if the court gets a chance to rule on the constitutionality, maybe it's a way to go at the Gun Free School Zone Act on constitutional grounds, because it'll be a Federal precedent. We just need East St. Louis not to back down like Warren County did.
