Should I confront them?

@Tom Cooper his comments were casual and your replies all read as accusatory and confrontational.

I have confronted tenants if police visits are made but not without them.

They are also demanding their rent back because they have left early and I would rather avoid an ugly confrontation in person.  

The last tip says don't be the owner so you can avoid more confrontations.

I confronted the tenant about why she had her bank pull back the transfer and during our heated conversation she claimed her bank gave her the option to pull back ALL of her transactions which would have been the deposit and 3 months rents!

My fiance is very non-confrontational so he wanted to let it go unless something worse happened.One thing I'll note here is that my fiance and I are very good tenants and kept the place in very good condition.

In such case, they would only have to pay us 1/2 the rent for the month of march.The picture requirement stemmed from a confrontation a few weeks back where he stated he did not want us in the apartment, knocking on his door, showing the unit, or otherwise any way disturbing him.

I had to involve the police when first floor ran screaming at me in my car on a public street, yanked open my passenger car door while I was in it, and entered the car screaming at me aggressively while I was calling 911, (all because we had made every effort to avoid a confrontation with her), but the police only went to warn her, did not arrest her.  

I've worked with very few confrontational sellers, but this fellow is different.
