Article 8 of the ECHR seems to require a court orders of some kind:

Not all European countries have the same exact rules as the US, some have stronger privacy in some areas and some have weaker in some areas.

But the US isn't exactly a poster child for privacy. Granted US rights on unlawful searches are for the most part decent.

> In England and Wales, a local magistrate issues search warrants, which require that a constable provide evidence that supports the warrant application. In the majority of cases where police already hold someone in custody, police can search premises without a search warrant under Section 18 of the Police and Criminal Evidence Act (PACE), which requires only the authority of an inspector.

> Under Section 18(5)a of PACE, a constable can conduct a search immediately without an inspector's authorisation. This subsection allows a constable to search the home of a suspect(s) under arrest in their presence before they take the suspect to a police station (or other custody location). Under Section 32 of PACE, a constable who arrests a person who is on their own property or has just left their premises, may immediately search both the suspect and the immediate area.

At no point did I say that the US is a "poster child for privacy," but the laws work differently.

The general concept is the same. Your original comments said:

> "not everyone has rules where the police need a warrant to search your home or vehicle".

EU membership nations have laws that require search warrants in some form. Most exceptions to this are reasonable, narrow and well defined. Similar to exceptions in the US: https://en.wikipedia.org/wiki/Warrantless_searches_in_the_Un...

Your original comment:

> "not everyone has rules where the police need a warrant to search your home or vehicle".

Suggests that this is not the case in Europe.
