Key legal question
Whether the cantonally found facts were arbitrary, especially as to the tenant's post-conviction conduct toward neighbors and victims' families.
Extracted holding
No arbitrariness was shown; the appellate court could rely on converging witness testimony, including testimony from neighbors.
Extracted reasoning
The challenged findings were supported by several consistent testimonies, including those of neighbors heard under oath; the federal court found no manifestly untenable assessment of the evidence.
