Legal Question in Landlord & Tenant Law in Illinois

Re: displayingusaflagonwindsows

Check your lease. If there is a provision in your lease that says nothing is to be displayed in the windows, then you must adhere to it. However, exceptions are often made for the diplay of the American flag, but do you really want to get evicted and then sue the landlord just to make your point?

And I'm not familiar with any right conferred under the Constitution that guarantees you the right to display a flag.
