I doubt signs will deter these people. They we’ll tear the sign down and claim they didn’t see the sign. Florida has now passed an anti squatter law. Gee why don’t other states? Well because blue state Democrats think criminals need more rights than law abiding citizens.
The democrat grifters cater to the “downtrodden” while making more people downtrodden with purposeful destructive financial policies. Disgusting anti American spirit.
If signs were any good, we would just put up signs on our borders!
