Imagine this… you’ve been a landlord for years, and have become quite well versed at evicting tenants who don’t pay their rent.
You purchase a new property. But when you open the door and find people living there. They don’t have a lease, the place reeks of urine, and there is a giant dog who looks like it’s going to bite your face off. You tell everyone to get out, and they laugh at you. Is that a needle on the floor?
What’s going on here? This is your property, they’re trespassers, and this is illegal! So, you call the police, who show up at your property.
