so it is not about deposit

if it is not about your deposit, then maybe your subject is somewhat confusing. "Your freedom to swing your fist ends right in front of my nose." Therefore, if you are seriously intimidated, you might consider calling the police again. The couple can at least be 'educated' once more. Law suit is definitely unnecessary because of its cost. Themis is blind, but her libra is not cheap. Next time ask clearly your landlord issues related with tenancy. If you and your landlord were to agree those items in the first place, you would not have such a trouble. Take it easy:)
