OK, I see you are a local. if the house has no number, then EXTRA care is incumbent upon the server to be sure he has the proper address. Due diligence is incumbent upon the officer when the stakes and risk is that high.
You people cannot have it both ways. The officer was probably serving a traffic warrant or some other low misdemeanor in which case the officer usually goes alone to prevent any appearance of over-reaching that so many here complain about. Was he suppose to take a SWAT team or 2-3 more cars, then you all would be railing on all that man power for one arrest.
Which is it? Try and knock on a door calmly and serve a paper or bring the cavalry and raze the property?
