I'm amazed at how many people on this thread do not realize the Bill of Rights applies only to the Government.
Just remember how many people have signed up at FreeRepublic, thinking because of the first amendment that they could say anything they wanted to say here and not get booted.
I'm amazed at both sides!
Civil rights can't be violated by private companies anymore. "No blacks allowed" is verboten. That is true.
Yes, the BoR was meant to apply only to the government. Nothing more certain.
Nevertheless, the whole thing is up to the judge these days. Constitution, BoR -- pff! Civil rights, freedom of association -- pff!
And I'll tell you what the judge will say, 99 times out of a hundred. He'll say the landlord has to suck it up. Regardless of right, wrong, common sense, lease, or his opinion on 2A...he'll say the landlord is the bad guy. The reason is beside the point, although the usual reason is that tenants have all the rights not specifically forfeited by them in their lease...and sometimes they have those rights too! When a tenant signs a lease that says, for example, that he has to fix a clogged toilet by himself at his own expense, most judges will say the landlord still has the legal obligation. In other words, even the lease isn't the final say. The judge has final say.
Only a fanatically anti-gun judge would side with the landlord here.
The law? So 18th c.
