I had a couple speeding ticket cases this morning in Albany City Court. Each was with a different State Trooper. Neither showed up, and the cases were dismissed.
In my experience it is very rare for a Trooper not to show. Happens maybe 5% of the time, maybe less. So that makes the odds of this day being 1 in 400. On the other hand, I suppose I can expect this to happen about every 400 times I go to Court with two cases.
