From my very first comment:

The root of the hacker mindset is looking at alternative solutions that go against the common narrative. It sounds like this method worked out for OP, so it is worth considering. I don't think I personally would go down this path due to possible complications, its utter pettiness, and the fact it is very easy to silence phones at off hours. But depending on the situation, maybe it would make sense.
I am a very moral person, hence having thought these things through. You're the one taking the shortcut of assuming anything done through "proper procedure" is moral. In my book, calling the cops on someone is most certainly escalating the situation and causing them personal stress. Deferring to the system is not an absolution from moral reasoning.
