In the case of an arrest warrant that'd usually be a knock and talk, unless we have surveillance showing you in the place which gives us PC to enter.
News is still reporting this as the service of a search warrant, which is a different case. The SW is for that address for a reason, which a judge agreed to. We don't know what the reason is yet, so it's impossible to guess whether "more care should have been taken", as several people are assuming is the case.
