Laws vary from state to state, and sometimes even between jurisdictions within a state. In Nebraska for example, yes I can get the permit, but the law governing that permit says that any private property owner may prohibit persons from carrying on their property by simply posting this sign: https://statepatrol.nebraska.gov/vimages/shared/vnews/storie... . If I want to be a law abiding gun owner I have to respect that (despite the fact that it is silly), otherwise I could have the permit revoked, and possibly face other legal repercussions.
