What is the test for determining whether a search or seizure was conducted in a reasonable manner at the point of a second entry?

^9. In examining whether the officers conducted the search or seizure in a reasonable manner at the point of the second entry, we do not focus on the amount of force they employed to force open the door (considerable) and that they did so with their firearms drawn (itself a significant use of force). See footnote 3, supra. Rather, we focus on their critical decision to enter at all. See Alexander v. City & Cnty. of San Francisco, 29 F.3d 1355, 136667 (9th Cir.1994) (holding that there were triable issues as to whether officers used excessive force by storming the house of a mentally ill recluse who had threatened to shoot anybody who entered).
