Broadly agree. Would probably be much cleaner all around if in such cases the law dictated possession back to the property owner with ~ treble damages/attorney

Broadly agree. Would probably be much cleaner all around if in such cases the law dictated possession back to the property owner with ~ treble damages/attorney's fees/statutory damages/reversion of possession in the cases where the alleged squatter was lawfully occupying. Basically enough to entice a lawyer to take the case on contingency and make it unequivocally in the favor of a hypothetically wronged tenant, while not allowing squatters to abuse the existing legal process.
