Need to put a stop to these people!

My neighbor tried to stop a man trespassing onto his rental property earlier today and was in return harassed by the man! Who do these people think they are anyway? Scaling fences of private property and helping themselves, now even in broad daylight and coming face to face with the home owners. I respect our local law enforcement, but sad to say, they aren’t of any help in these situations , as they are to backed up with other crimes and issues for which they have no man power to handle. So now home owners literally have to take matters into their our own hands. These criminals need to have a wake up call and be shown that they will not get away with this anymore. So sad...
