Statutes exist to allow people to take emergency action when a crime is in the process of being committed - but they have no relation to civil forfeiture, which isn't about stopping an action but to remove peripheral resources permanently.
Why do you keep going on about civil forfeiture? That is not what I have been talking about at all. So you are opposed to it, so am I in many respects.
Shutting down hott_kiddie_porn_pix_4_free.com is quite different from impounding someone's car or putting a lien on a bank account. Please stop arguing with me about the latter when I have only ever been talking about the former.
But none of them relate to your example.
