This could be remedied if realtors/rental agencies filed copies of all contracts with the county/city. Make sure you understand, I am NOT suggesting the county/city keep a database of rental properties, etc. I am suggesting they file it for the record (as you can do with your DD-214; that way if you ever lose your DD-214, instead of begging the VA for it, you could simply go down to your local county records building and they would pull you up a CERTIFIED COPY of your DD-214).
Then, when someone shows a fake lease, the county/city would be able to quickly and easily see this is FAKE because it was never filed for the record and then it is a criminal trespass.
Attacks on private property are attacks on civilization.
