Police and legal system collecting high pay from taxpayers and sleeping on the job
If a burglar enter your house without permission, can be arrested and charge on the spot for burglary and trespassing
If someone did not pay rent, under the law, he no longer has permission to stay on the property. That is trespassing. Using the owner's water, electricity and the property without paying, that is considered stealing.
Either way, it's perfectly within the police's power to arrest on the spot for breaking in without owner's permission
Someone trying to avoid paperwork by taichi-ing the case elsewhere and leaving landlords at mercy of the thieving tenants.
